Stephanie L. Gaw, MD, PhD

Assistant Professor
Maternal Fetal Medicine, Obstetrics, Gynecology, and Reproductive Sciences

Dr. Gaw is a practicing Maternal-Fetal Medicine physician and scientist who studies the impact of infectious diseases on fetal growth and development, and particularly how this is mediated by the placenta. She has a long-standing interest in global health. She served as a Peace Corps volunteer in Honduras in 1998-2001. She has over 20 years of experience studying malaria both in the laboratory and in the field. She has led collaboratorative research in malaria in Uganda, Zika virus in Brazil, and most recently COVID-19 in pregnancy. Her work has been funded by the National Institutes of Health, the Reproductive Scientist Development Program, the Foundation for the Society for Maternal-Fetal Medicine, the Bill and Melinda Gates Foundation, and the CDC Foundation.

Sirirak Buarpung, DVM, PhD

Lab Manager

Dr. Buarpung is a graduate of veterinary medicine from Chulalongkorn University in Thailand. She earned her doctorate in the Department of Obstetrics, Gynaecology and Reproduction, studying male gamete preservation and assisted reproductive technologies aiming to develop the techniques for endangered wild felids conservation. After her postdoctoral training, Dr. Buarpung worked in a fertility clinic for 2 years. She worked on preimplantation genetic screening and assisted with operational workflow. With all that, she has become fascinated by the science of pregnancy. Dr.Buarpung joined the Gaw Lab in 2018 and supports all of the projects in the group. 

Lin Li, MD, PhD

Postdoctoral Research Associate

Dr. Li graduated from Zhongshan Medical School of Sun Yat-sen University in China. She then went on to earn her PhD in Fetal Medicine, focusing on prenatal diagnosis and twin pregnancies. For her graduate work, she studied the regulation role of microRNA in trophoblast function and placentation in monochorionic twins. She is interested in placental development and its impact on maternal and fetal health. Dr. Li joined the Gaw Lab in 2021 and is working on the COVID-19 infection in pregnancy, and the immune response to COVID-19 in the mother and fetus. 

Nida Ozarslan, MD

Postdoctoral Research Associate

Dr. Ozarslan first joined the Gaw Lab in 2017 as a visiting summer research volunteer while pursuing her medical studies at Marmara University School of Medicine in Instanbul, Turkey.   She continued her work on RNAseq analysis of maternal monocytes and fetal Hofbauer cells in placental malaria throughout the rest of her medical education, and graduated in June 2021. She joined the Gaw Lab as a postdoctoral researcher in October 2021, to continue her work on malaria in pregnancy, and the impact on maternal-fetal inflammation on pregnancy outcomes.  

Christine Lin

Clinical Research Coordinator

Christine is a Truman State University graduate with a degree in Biology and Health Studies.  Her work as a research coordinator on the multi-center PRIORITY Biospecimen Study focuses on the management of a biorepository of specimens from COVID-19 affected mother-baby dyads across the country.  Prior to joining the Gaw Lab in 2019, Christine had extensive experience working in women's health: as a clinical assistant in the UCSF Prenatal Diagnostic Center and as a reproductive health coordinator at Planned Parenthood.  Christine is passionate about reproductive justice and contributing to research that will improve birth outcomes for mothers and babies worldwide.

Dr. Gonzalez is a second year maternal-fetal medicine fellow at UCSF. She graduated from UCSF School of Medicine, and completed her residency in OB/GYN at Dell Medical School, University of Texas at Austin. She is interested in understanding how infections and the environment impact pregnancy, particularly in underrepresented ethnic minorities. Her primary project is investigating inflammatory responses in mother/infant dyads affected by COVID-19, for which she was awarded a 2021 UCSF CTSI Pilot Award. She is also investigating interactions between Zika virus infection and pesticide exposures using a human placental explant model. She joined the Gaw Lab in 2019.

Emilia Basilio, MD, MPH

She has continued to work in the Gaw Lab in projects related to COVID-19 in pregnancy and placental explants as ex vivo models of inflammation. She is also an active member of the U.S. Air Force Reserve.

Raha Sadeghi

Staff Research Associate

Raha graduated from University of San Francisco with a BS in biology and double minor in chemistry and health studies. She joined the Gaw lab during her senior year as an undergraduate researcher and is currently working on the projects related to COVID-19.
