Changing women’s lives by uncovering the complexities of the female pelvic floor
Dr. Alperin’s expertise as a practicing, board-certified female pelvic medicine specialist places her in a unique position, in which her clinical and surgical understanding help guide the directions of the Alperin Lab’s basic science and translational studies to answer the most relevant questions. Alperin laboratory uses a multi-prong approach to study the impact of pregnancy, birth injury, and aging on the structure, function, plasticity , and regenerative potential of the female pelvic soft tissues. The results of our studies, facilitated by the interdisciplinary approach, will improve our understanding of the transition of female pelvic soft tissues from a physiological to a pathological state, which in turn will have major implications on the development of effective preventative and mitigating strategies. Ultimately, we hope that this research will help reduce the epidemic of pelvic floor disorders and improve the lives of millions of women.
Dr. Alperin is a practicing female pelvic medicine and reconstructive surgery (FPMRS) specialist with expertise in basic science and clinical research. Her overarching goal is to facilitate the highest quality patient care through mechanistic research and the cultivation of interactions between basic, translational, and clinical scientists and health care providers from various disciplines with a shared interest in women’s health. She completed residency in Obstetrics and Gynecology at Brigham and Women’s Hospital, Harvard School of Medicine and FPMRS fellowship at the University of Pittsburgh, where she had also obtained a Master’s degree in Clinical Research. Throughout her career, she has actively pursued and organized multi-disciplinary research programs and has worked closely with experts from disparate fields from bioengineering to stem cell biology. Alperin lab aims to shift the current research paradigm in female pelvic medicine towards more mechanistic studies, ultimately improving the lives of women suffering from pelvic floor disorders through innovative preventative and therapeutic strategies.
Michelle Wong, BS Senior Research Assistant
Michelle earned her B.S in Biology from California Institute of Technology in 2017. Her research interest lies in the pathophysiology of pelvic floor dysfunction, and she currently studies the impact of age on pelvic floor muscles. She plans to attend medical school in 2020 where she hopes she can continue addressing clinical problems through basic science research. In her free time, she enjoys basketball, hiking, and cooking.
Francesca obtained her PhD in Biomedical Sciences at Sanford Burnham Prebys Medical Discovery Institute, after which she had joined the Alperin lab as a postdoc in 2018. She is interested in investigating the role of muscle stem cells in the pelvic floor muscles’ plasticity during pregnancy. When out of the lab, Francesca loves cooking for her friends and enjoys outdoor activities in beautiful San Diego.

Emmy Do Masters Student
Emmy began research in the Alperin lab as an undergraduate student at UCSD majoring in Biochemistry and Cell Biology. She is now completing her Masters and is interested in pursuing a career in biological research related to immunochemistry and women’s health issues. When not in lab, she enjoys cooking, being with family, and watching TV shows/movies with her dog.
Varsha Rajesh Undergraduate Student
Varsha is an undergraduate student at UCSD, majoring in Biochemistry and Cell Biology. She is interested in learning biochemical techniques and how they apply to various fields such as women’s health, forensics and astrobiology. In her free time, she likes doing art and watching movies.
Tatiana Catanzarite, MD MS
Tatiana completed her undergraduate studies at Stanford University and then medical school at University of California at Davis. She then pursued residency training in OB/GYN at Northwestern University in Chicago, IL, followed by fellowship training in Female Pelvic Medicine and Reconstructive Surgery (FPMRS) at the University of California, San Diego – Kaiser San Diego program, after which she joined the FPMRS faculty at UCSD. During fellowship, she was delighted to have the opportunity to work in the Alperin lab studying mechanisms of muscle injury at the time of vaginal birth and hopes that this work will ultimately contribute to deeper understandings of the contribution of muscle injury/recovery in the development of pelvic floor disorders in women.
Amanda Artsen, MD
Amanda completed Ob/Gyn residency at the University of California, San Diego, where she studied the muscle architecture of rhesus macaque pelvic floor muscles and the human external anal sphincter. She is now at the University of Pittsburgh Medical Center pursuing her FPMRS fellowship and is studying the immunology of polypropylene mesh complications. She loves long distance running and singing and dancing with her toddler.
Tim Kaddis, BS
Tim is currently a medical student at UCLA School of Medicine, He first got involved with the Alperin lab during his senior year at UC San Diego, and over the next couple of years he had worked on multiple projects designed to further understanding of the composition & physiology of the pelvic floor muscles. Through these projects, he was able to perfect a variety of laboratory techniques, learn a framework for effective research, and ultimately, contribute to the growing body of knowledge in the important field, such as female pelvic medicine.
Neil Aiad, BS
Neil graduated from UCSD with a B.S degree in Bioengineering. While in the Algerian Lab, he studied biomechanics with regards to active force generation in pelvic floor muscles. He enjoys running and listening to music in his free time.
