Christopher Marshall

Research Specialist 1
Email: christopher.marshall@nih.gov

Chris is a research specialist with the Sheppard Lab. He has 9 years of experience in the NICHD zebrafish facilities where he formerly worked as the Animal Health Specialist and more recently as the Technical Trainer for the husbandry team. Prior to working with zebrafish, Chris studied organismal biology and ecology at Towson University where he received his B.A. in Biology in December 2011. During his time at Towson, he interned with the Maryland Department of the Environment in a lab that specialized in habitat assessments. His current goal is to transition his knowledge of zebrafish and the NICHD program into a role which directly supports the research of the Sheppard lab while also developing his own skills as a researcher. He is an avid outdoorsman, a DC sports fan, and a proud father of two.

Luciana Daniela Garlisi Torales, MD

Visiting Post-doctoral Fellow
Email: luciana.garlisi@nih.gov

Daniela is a visiting postdoctoral fellow in the Sheppard lab. She is an international medical graduate from Paraguay, and received her MD in 2022 from Facultad de Ciencias Medicas – Universidad del Pacifico. Her passion for research started in her second year of medical school when she worked with medicinal plants. She studied the impact of COVID-19 on medical education in Latin America. She is passionate about empowering other students to do research in Latin America. She is interested in doing clinical research in her country in the future.

Andrea Bowling, MSN, APRN, FNP-C

Nurse Practitioner
Email: Andrea.bowling@nih.gov

Andrea Bowling is a Family Nurse Practitioner who has been with NIH for the past 4 years. She initially began working for the National Institute of Neurological Disorders and Stroke (NINDS), working in neurosurgery with adults with incurable pain, then at National Human Genome Research Institute (NHGRI) with adult genetic disorders before moving to Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). She works with the Unit on Vascular Malformations on a natural history study for patients with lymphatic anomalies and also consults on other clinical protocols. She obtained her MSN from Georgetown University, and her RN from Stevenson University and is currently in the process of obtaining her DNP as a Psych Mental Health Nurse Practitioner. She has always loved research and would like to become a principal investigator, working on research dealing with the psychosocial perspective of patients with chronic illnesses. In her free time, she loves spending time with her family and friends, reading, and traveling.

Georgia Krikorian

Postbaccalaureate Fellow
Email: georgia.krikorian@nih.gov

Georgia is an OITE-PEP postbaccalaureate fellow at the NICHD examining lymphatic vasculature development and underlying mechanisms of lymphatic anomalies, particularly using organoid modeling and the bench-to-bedside model. Before joining the NICHD, she studied at Smith College in Northampton, MA where she received her B.A. in Biochemistry in May 2022. Her passion for research was established during her undergraduate career in the laboratory of Michael Barresi, where she studied the regulation of radial glia development during neurogenesis in zebrafish. She is motivated to pursue an MD-PhD degree program and career as a physician-scientist where she hopes to utilize the tools of basic research to innovate new treatment modalities for complex conditions.  

Dhyanam Shukla

Postbaccalaureate Fellow
Email: Dhyanam.shukla@nih.gov

Dhyanam is a postbaccalaureate fellow working at the NICHD trying to understand the complexities of CCLA in zebrafish models. He graduated from Rutgers University in 2021 with a B.A. in Cellular Biology and Neuroscience and a minor in Psychology. His interest in research stemmed as an undergraduate when he studied congenital muscular dystrophy at the Child Health Institute, and ever since then he has been passionate about learning developmental biology, neurobiology, and zebrafish research. In his free time, he loves to cook, bake, look after many plants and explore DC.

Kristina Woodis

Postbaccalaureate Fellow
Email: kristina.woodis@nih.gov

Krissy is a postbaccalaureate fellow working at the NICHD examining lymphatic anomalies in zebrafish. She recently graduated from Elon University with a B.S. in Biology with a concentration in Foundational Medical Science and a minor in Psychology, where she studied the involvement of the gut-brain axis in epilepsy in zebrafish. She is passionate about studying neurobiological disorders in the zebrafish model and is eager to apply this knowledge clinically. Her career goal is to become a physician-scientist. In her free time, Krissy loves to practice yoga, read, cook, and enjoy time outside with friends.

Scott Paulissen, PhD

Researcher - Lab Manager
Email: Scott.Paulissen@nih.gov

Scott is the lab manager and a researcher in the Sheppard lab. His work focuses on the molecular and cellular mechanisms causing KRAS-related central conducting lymphatic anomaly. He also studies the causes and progression of capillary malformations with undergrowth using the zebrafish equivalent of the mammalian forelimb, the pectoral fin. Scott is a developmental biologist who completed his post-doctoral fellowship in Brant Weinstein’s lab at NICHD, focused on the development and pathways responsible for the forelimb vasculature in zebrafish. Prior to arriving at the NIH, he received his bachelor’s degree at Nevada State College in Biology, and later received his PhD in molecular biology at the University of Massachusetts - Boston in the lab of Linda S Huang. He has wide ranging interests including but far from limited to, history, movies, a fairly eclectic range of music, sports, and playing with his daughter.

Kamyab Pirouz

Summer Intern (2022)
Email: Kamyab.pirouz@nih.gov

Kamyab is a summer intern examining genetic causes of CCLA. He is a third-year honors student studying biology at Northeastern University in Boston. His career goal is to one day become a physician and travel the world helping patients in underserved and underprivileged communities. Kamyab was born in Iran, moved to Ottawa, Canada at the age of 2, and then moved to Bethesda, MD at the age of 5. Kamyab loved the childhood he had here, and grew up with an immense passion for soccer, a sport he still plays competitively to this day. He enjoy outdoor activities, trying random things he has not done before, and spending time with friends and family. He will be graduating from Northeastern in December 2023 and aims to begin medical school the following year.
