Through their advancements in disciplines ranging from nuclear physics and biochemistry to engineering, mathematics, mental health and nanoscience, these women exemplify a Temple Made spirit of innovation, excellence and leadership.

Lauren Alloy 

Laura H. Carnell Professor of Psychology and Neuroscience, College of Liberal Arts 

Research focus: Understanding the cognitive, psychosocial, developmental and neurobiological processes involved in the onset and course of depressive and bipolar disorders 

How it started: Lauren Alloy first became interested in the causes of depression while a doctoral student at the University of Pennsylvania, where she was inspired by her PhD mentor’s work applying an animal model of learned helplessness to human depression. As her career progressed, including her time as an assistant to full professor at Northwestern University, she expanded her research to include bipolar disorder. 

She’s spent much of her career trying to answer a central question: Why are some individuals vulnerable to depression and bipolar disorder, while others remain resilient? Alloy has developed numerous theories and conducted research to help better understand the mechanisms causing depression and bipolar disorder. Her work has helped shape the field’s understanding of these conditions, with important implications for early identification, prevention and treatment. 

Alloy has authored more than 460 publications in scientific journals spanning psychology, psychiatry and neuroscience. Her contributions have earned her several distinguished scientist or lifetime achievement awards from professional organizations and scientific societies. 

Courses taught: PhD-level Grant Writing 

Advice for other women in STEM: “Early in my career there were very few women faculty in my field. I was the first and youngest woman full professor in the history of the Psychology Department at Northwestern University. I did encounter some bias, patronizing and harassment, particularly as a young woman, but thanks to my passion for research and mentorship of students, I never let those negative experiences stop me. I learned to develop a thick skin, be resilient and persist in my work and my goals. Today, my advice for women in STEM fields is to persist and pursue the research you are passionate about and don’t allow obstacles to stop you.”

Martha Constantinou   

Associate professor and vice chair, Department of Physics, College of Science and Technology  

Research focus: Using theoretical and computational nuclear physics to learn more about the fundamental particles that make up the visible universe  

How it started: As a high school student, Martha Constantinou was fascinated by everyday phenomena, such as the illusion of a broken straw in a glass of water, which can be explained by the laws of physics. This interest made her want to learn more about theoretical physics in college. She was especially intrigued by computational nuclear physics, because it combines complex theory, mathematical methods and high-performance computing. The main goal of her research is to learn more about the composition and behavior of fundamental particles that make up the visible universe.  

Today, she serves as lead principal investigator for a U.S. Department of Energy-funded project to study the fundamental building blocks of the visible universe, quarks and gluons. The collaboration is a consortium of scientists from 11 universities and three national laboratories.  

Constantinou’s research has been published in the Physical Review Letters of the American Physical Society, the Journal of High Energy Physics, Nature Communications and the European Physical Journal.  

Courses taught: General Physics I and II for Honors students  

Advice for other women in STEM: “My experience as a woman in STEM has been influenced by a lack of female mentors in academic settings and constant advice to consider alternative career paths. Despite these challenges, I am grateful that I persisted in pursuing a career in academia. My message to all women considering a STEM field is to not let fear hold them back from following their passion and carving out their unique path.” 

Julie Drzymalski   

Professor of instruction and director, Department of Engineering, Technology and Management, College of Engineering  

Research focus: Developing human-centered models to improve public services  

How it started: For many years, Julie Drzymalski worked as a construction project manager, where it was important to see the bigger picture, including how all decisions affect the outcome of a project. As she transitioned out of that industry, she knew she wanted to focus on “big picture” engineering and not on technical design. This led her to industrial and systems engineering (ISE), which involves designing, developing and optimizing systems for products and services that span many industries, such as manufacturing, defense, healthcare and finance, to name a few.  

In the classroom, Drzymalski enjoys watching her students make connections between coursework and the real world. She emphasizes incorporating necessary but untraditional engineering topics into the curriculum such as human modeling, equity and artificial intelligence, to best serve her students. By introducing students to industry partners, a variety of career paths and nonstop teamwork, the College of Engineering’s ISE program creates a sense of social capital that forms a sense of community, which she believes particularly benefits women in ISE.  

Her research has been published in the Journal for Systems Science and Systems Engineering, and the Proceedings for IISE International Conference and the ASEE International Conference.  

Courses taught: Product Quality Assurance, Stochastic Models in Operations Research, Systems Thinking and Modeling, Industrial Simulation, and Industrial and Systems Engineering Senior Design Project I  

Advice for other women in STEM: “Understand that everyone struggles, and one mistake does not define who you are. While it may be challenging at times, do not be afraid to speak up—for yourself and for future women in STEM—and never underestimate your self-worth.” 

Carol Manhart   

Associate professor, Department of Chemistry, College of Science and Technology  

Research focus: Using biochemistry to understand how typos are corrected during the DNA copying process and predict the likelihood of cancer developing  

How it started: Growing up, Carol Manhart was always curious about the inner workings of things around her. She recalls a vivid childhood memory in which her dad was fixing a door in their home. Manhart found herself captivated by the mechanisms of the deadbolt lock, and she felt a strong desire to dismantle it to get a better understanding of how it works.  

That sense of wonder grew and intensified during her college years, particularly as she took more biology courses. Today, her work focuses on the DNA copying process. DNA uses a kind of spellchecking system involving proteins that detect, remove and correct typos that can cause mutations and lead to diseases such as cancer. Her lab uses biochemistry to understand how proteins interact with DNA to correct typos and predict the likelihood of acquiring a cancer associated with a defective protein.  

Manhart’s research has been published in journals such as the Encyclopedia of Biochemistry, Nucleic Acids Research, Nature Communications and PLOS Biology.  

Courses taught: Biochemistry at the undergraduate and graduate levels  

Advice for other women in STEM: “If I could offer advice to women aspiring to excel in STEM fields, I would strongly recommend seeking out mentors and sponsors. It is crucial to connect with individuals who can provide guidance and support, as well as advocate for you to flourish in your career. During my undergraduate and graduate studies, I distinctly recall being surrounded by a significant number of women in my classes, yet there were very few women professors. I remember struggling to envision myself as a STEM professor due to the scarcity of role models.”

Irina Mitrea   

Laura H. Carnell Professor of Mathematics, College of Science and Technology  

Research focus: Solving complex math problems using a method called singular integral operators  

How it started: Irina Mitrea has always been interested in mathematics and fascinated by every single effort to push the boundary of what is known and understood. As she advanced in her career, she worked with mega structures and focused on bringing together different areas of math that were once thought to be separate. Figuring out how geometry, analysis and algebra can work together in unison to solve partial differential equations and model physical phenomena has been a guiding light throughout Mitrea’s career.

Today, she studies how different mathematical areas like harmonic analysis, partial differential equations and geometric measure theory come together. Her research focuses on solving complex math problems using a method called singular integral operators.  

She has had more than 60 research articles published in top journals such as Advances in Mathematics, Analysis and PDE, Notices of the American Mathematical Society, and the Journal of Functional Analysis. She also recently published the Geometric Harmonic Analysis five volume series, a monumental mathematical tour de force which has been 15 years in the making. The series introduces a new and sophisticated theory for answering very difficult mathematics questions, and she expects it to serve as a platform for future research at the crossroads between geometry and harmonic analysis.  

Courses taught: Advanced Calculus I and II, Partial Differential Equations, Singular Integrals for Elliptic Boundary Value Problems, and Harmonic Analysis  

Advice for other women in STEM: “Believe in yourself and always take initiative. Good things come from being proactive. Be aware that even what turns out in the end to be a bright idea starts really small and takes a lot of time to develop. Nurture those small thoughts and intuitions until they are fully formed. And surround yourself with people who support you and inspire you. I personally am so hopeful seeing the extraordinary talent of the younger generation of women in mathematics and so grateful for the work they do every day to help redraw professional norms for a more inclusive and diverse mathematical community.”

Elham Sahraei 

Associate professor, Department of Mechanical Engineering, College of Engineering 

Research focus: Improving the safety of lithium-ion batteries under extreme conditions and advancing crash safety modeling for electric vehicle batteries 

How it started: Before the days of electric vehicles (EVs), Elham Sahraei’s research focused on automotive crash safety and occupancy protection. But as EVs started entering the market, Sahraei became interested in how the addition of batteries might change vehicle crash outcomes, and she began studying how lithium-ion batteries behave under mechanical stress and extreme conditions. 

Today, Sahraei directs Temple’s Electric Vehicle Safety Lab and the Center for Battery Safety, where she collaborates with partners across the vehicle and software industries, as well as government agencies, to conduct research and develop tools for crash safety characterization and modeling of lithium-ion batteries. 

Her research has been published in the Journal of Energy Storage, Energy Reports and the Journal of Mechanical Sciences. She has also been named to Stanford/Elsevier’s list of the world’s top 2% of scientists in the subfield of energy for the past five years. 

Course taught: Solid Mechanics, Finite Element Modeling, Impact and Crashworthiness, and Machine Design 

Advice for other women in STEM: “I’m often the only woman in technical meetings or workshops in my field, but that has never limited my contributions or my ability to earn the respect of my peers. I hope for a future where women no longer question their place in STEM—where they know they belong at every technical and intellectual table, in any role they choose.” 

Karin Wang   

Assistant professor, Bioengineering Department, College of Engineering  

Research focus: Understanding how cell and matrix mechanobiology can be used in wound healing and cancer treatment  

How it started: When Karin Wang began her undergraduate studies in biomedical engineering, she did not anticipate that an introductory chemistry course would lead to collaborating with professors to create meshlike structures that help repair tissues in the body, like fixing hernias or damaged blood vessels. The experience was so rewarding that she continued to learn more about biomaterials and cell behavior, with the goal of one day running her own research lab where she could continue to ask questions about how our body maintains tissue homeostasis or drives disease progression.   

Today, her work focuses on how cells create their own matrix protein scaffold networks to close wounds or to facilitate fibrosis or metastasis. In her lab, she combines engineering, materials science and cell biology to create platforms and tools that help us see how cells and matrix networks behave together. Her aim is to understand and stop harmful interactions between cells and their environment, which could lead to conditions like fibrosis or cancer.   

Wang’s lab was awarded a Blue Sky Initiative Award from Temple’s Office of the Vice President for Research to investigate how ancestry influences cell migration and matrix network organization during wound closure. Her lab has also received a Medical Research Program Grant from the W.W. Smith Charitable Trust to study how signals from the surrounding tissue contribute to breast cancer spreading. 

Her research has been published in Cellular and Molecular Bioengineering, ACS Biomaterials Science and Engineering, and the American Journal of Physiology-Cell Physiology.  

Courses taught: Biomaterials, Introduction to Bioengineering, Mechanobiology and Bioengineering Graduate Seminar  

Advice for other women in STEM: “Find awesome mentors and friends, and make sure to put in the work to maintain a relationship with them. They are your network that will advocate for you, push you to overcome obstacles and celebrate successes with you.” 

Kallie Willets 

Professor, Department of Chemistry, College of Science and Technology 

Research focus: Exploring how metals such as gold and silver behave at the nanoscale, particularly how they interact with light 

How it started: Kallie Willets has long been fascinated by how materials interact with light and how light can be used to study phenomena too small to be seen with the naked eye. Metals became of particular interest to her, thanks to their ability to change color at scales more than 1,000 times smaller than the width of a human hair. Understanding why that happens and how that property can be exploited initially drew her into the field of nanoscience. 

Willets recently joined a $20 million research project funded by the National Science Foundation focused on nanocrystals. Alongside researchers from eight other institutions, Willets is exploring how nanocrystals behave, and the research could have applications in biomedicine, electronics, fuel production, chemical manufacturing and other areas.  

Her lab has produced more than 100 peer-reviewed publications, mostly in journals that focus on nanoscience as well as physical and analytical chemistry. In addition to her research, Willets and her research team are deeply involved in outreach and education, working with local teachers and students and inviting them into the lab to experience nanoscience firsthand. 

Courses taught: Original Research Proposal Preparation 

Advice for other women in STEM: “I wouldn’t be where I am today without an excellent network of mentors. My mentors have ranged from formal (my advisors) to informal (a close group of faculty friends in other departments) to unexpected (students that work in my lab). Science is a team sport, so keep an eye out for excellent teammates! And don’t be afraid to say the words ‘I don’t know.’ I used to think admitting I didn’t know something was a sign of weakness, but it is actually a sign of strength. Saying ‘I don’t know’ provides the opportunity to learn something new—and it has allowed me to expand my research program and my impact in ways I would never have imagined!”
