Sokol, Jan studied Biomechanical Engineering as an undergraduate at Stanford and is pursuing an MS degree in Biomedical Informatics. Alongside his studies, one of the projects that he is working on in the Longaker Laboratory is to characterize fibroblast heterogeneity in human skin and find out its role in skin-scarring. He is Czech, grew up in Duesseldorf, likes to surf, read and eat spicy food. 

Struck, Danni recently graduated from University of California Berkeley, where she received her bachelor’s degree in Integrative Biology. She rowed for Cal all four years, and was a member of the 2016 NCAA Women’s Rowing Championship team. Danni’s research aims to study the bone fracture healing process and the effects of aging on skeletal stem cells and bone, cartilage and stromal progenitor cells in menopausal animal models. She is currently applying to medical school. In her free-time, Danni enjoys running, cooking and being near the water.


Talbott desJardins-Park, Heather is an MD/PhD student in the Stem Cell Biology and Regenerative Medicine program at Stanford and has been a member of the Longaker laboratory since 2017. Heather earned her AB in Chemistry from Harvard University, where she conducted research in organometallic catalyst synthesis. Currently, she investigates mechanisms of regenerative wound healing during embryonic development, with the ultimate goal of identifying novel targets for preventing fibrosis. In her free time, Heather enjoys singing (jazz and classical), surfing, and exploring the great outdoors.

Ruth Tevlin.jpg

Tevlin, Ruth is a surgical resident here with the Division of Plastic and Reconstructive Surgery. Originally from Dublin in Ireland, Ruth initially took two years out of her residency training with the Royal College of Surgeons in Ireland to complete postdoctoral research with Dr. Longaker from 2013-2015. During this time, she worked on characterization of the mouse skeletal stem cell as well as activation of stem cells in response to injury and in the setting of systemic disease. Her postdoctoral fellowship changed her career path significantly, inspiring her interest in regenerative medicine and tissue engineering. In 2017, Ruth moved back to the Farm and was delighted to restart residency training here at Stanford with the goal of becoming an academic Plastic Surgeon. Ruth is excited to be back in the Hagey lab this year, completing her Professional Development year under the mentorship of Dr Longaker. Her research is supported by a Plastic Surgery Foundation Fellowship Research Grant in addition to funding from the Transplant and Tissue Engineering Center of Excellence at Stanford University. Outside of the lab, Ruth enjoys spending time with her family and her friends, exploring the Bay Area, doing yoga, biking and working on her golf swing. 

Ashley Titan.JPG

Titan, Ashley is a categorical General Surgery resident at Stanford. She is interested in skeletal stem cell biology, fibrosis/scar formation, and tissue regeneration. Ashley attended Stanford University (where she captained the Division 1 Varsity Fencing Team) and majored in Philosophy with Honors in Ethics in Society; she earned her M.D. from Icahn School of Medicine at Mount Sinai. Outside of medicine, she enjoy triathlons, marathons, backpacking, and hiking with her boyfriend and her adorable 10 year old dog, Molly. 


Valencia, Caleb is currently a CIRM Scholar from California State University, Fullerton and during my time in the Longaker Lab I will be studying wound healing and fibrosis. My goal is to go to medical school after my internship. In my free time I hope to explore Northern California, play basketball, and some photography.
