Valentina greco - PI

Valentina was born in Palermo, Italy. Valentina was an undergraduate at the University of Palermo, Italy, got her PhD at the EMBL / MPI-CBG (Germany) (1998-2002) and did her post-doc  at the Rockefeller University (2003-2009). Valentina is currently an Associate Professor in the Genetics, Cell Biology and Dermatology Departments, and a member of the Yale Stem Cell Center and Yale Cancer Center at Yale University (2009-present). Valentina has been the recipient of several awards including the 2014 ISSCR-Outstanding Young Investigator Award, 2014 Women in Cell Biology Junior Award (WICB) for Excellence in Research from the American Society of Cell Biology (ASCB), the 2015 Robertson Stem Cell Investigator Award from the New York Stem Cell Foundation (NYSCF), 2015 Mallinckrodt Scholar Award, 2016 Early Career Award from ASCB, 2016 HHMI Faculty Scholar Award, 2017 Glenn Award for Research in Biological Mechanisms of Aging and the 2017 Class of 61 Cancer Research Award.


Jonathan Boucher - Research Assistant

Jon graduated from Boston University in 2014 with a BS in Human Physiology. He trained at Boston University School of Medicine under Tsuneya Ikezu and at Massachusetts General Hospital with Karleyton Evans. He joined the Greco Lab in June 2014 to further his knowledge in stem cell biology and hopes to pursue medical school or a PhD program in the future.


Catherine Martone - Lab Manager

Catherine received her BS in biology from McGill University in 2001. She began her research in Dr. Warren Shlomchik’s lab at Yale immediately after graduation by studying the shared mechanisms of T cell killing in GVL against different models of chronic myeloid leukemia (CML) and comparing their stem cells with the goal of understanding why some leukemias are GVL-sensitive and others GVL-resistant. She remained in Dr. Shlomchik’s lab until joining the Greco Lab in July 2015 as their lab manager.  


David Gonzalez - LAB MANAGER

Dave started working at Yale in 2004 as a Veterinary Technologist. After receiving his MHS from Quinnipiac University in 2008, he took over management of the In Vivo Imaging Facility here at Yale. There he specialized in developing and implementing novel surgical approaches utilizing two-photon microscopy to conduct 4D imaging studies in various model systems and tissues. Simultaneously, he also conducted his own research under Dr. Ann Haberman studying B cell differentiation during the early germinal center response. He joined the Greco lab in November 2015 after many years of successful collaborations.

Graduate Students


Cristiana Pineda - PhD Student

Cristiana is from Boston, Massachusetts. She graduated from Holy Cross in 2012 as a chemistry major with a biochemistry concentration. She then worked for a year as a technician at Massachusetts General Hospital in a molecular genetics cancer lab. Cristiana joined the Greco lab in May 2014 under Yale’s BBS MMPP program. In the lab, Cristiana is interested in mechanisms of tumor development and genetic characteristics of malignancy.

Edward Marsh - PhD Student

Edward received his BS in computer science from the University of Washington in 2007. He then worked as a software developer at until discovering his passion for cell biology in 2011. Edward worked as a research assistant at the Fred Hutchinson Cancer Research Center and then started his PhD studies at Yale in 2014, joining the Greco lab in March 2015. Edward is interested in understanding the mechanisms that control and modulate tissue regeneration.


Jessica Moore - PhD Student

Jessica received her B.S. in biology and German studies from Colby College. She then worked for two years as a technician at Boston Children’s Hospital studying hematopoiesis and clonality using zebrafish as a model organism. Jess began her PhD studies at Yale in the fall of 2016 and joined the Greco lab in March 2017. Now, she is interested in understanding the signaling processes governing epidermal homeostasis.



Sangbum Park - Postdoctoral Fellow

Sangbum received his B.S. in Animal Science in 2006 and Ph.D. in Biological Science in 2012 from the Seoul National University, South Korea. For his Ph.D. he focused on modulation of self-renewal and differentiation capability in human mesenchymal stem cells. Sangbum joined the Greco Lab May 2013. In the Greco Lab, he is interested in studying stem cell decisions in the skin during wound healing by live imaging. Sangbum was awarded the Brown-Coxe Fellowship and the CT Innovation seed grant. Congratulations!

Tianchi Xin - Postdoctoral Associate

Tianchi is from China. He received his B.S. degree in biology from Nanjing Normal University in 2006. Then he did research in stem cell and developmental biology in Shanghai Jiao Tong University and received his Ph.D. degree in 2014. Tianchi joined Greco Lab in May 2014. He is interested in studying the signaling mechanisms underlying hair follicle regeneration and stem cell regulation by molecular and genetic methods. Tianchi got awarded of the Brown-Coxe Fellowship. Congratulations!

Katie C.jpeg

Katherine Cockburn - Postdoctoral Fellow

Katie received her BS from the University of British Columbia and her PhD from the University of Toronto. She performed her doctoral work in the lab of Dr. Janet Rossant, where she studied lineage specification in the preimplantation mouse embryo. Katie joined the Greco lab in June 2015, and she is interested in the relationship between cell signaling and cell behaviour during regeneration of the hair follicle. Katie got awarded the CIHR Fellowship. Congratulations!


Sara Gallini - Postdoctoral Fellow

Sara received her B.S. and M.S. degrees in Biotechnology and Medical Biotechnology from the University of Bologna and her PhD in Molecular Medicine from the University of Milan. She performed her doctoral work at the European Institute of Oncology (IEO) in Milan in the lab of Dr. Marina Mapelli. The main findings of her Ph.D. research include the identification and functional characterization of the novel mitotic spindle orientation functions of Aurora-A kinase and of the actin-binding protein Afadin. Sara joined the Greco lab in October 2016, and she is interested in elucidating the cellular behaviors of wound repair that promote skin cancer initiation.


Anupama Hemalatha - Postdoctoral Associate

Anupama received her B.S. in Zoology from Kerala, India and M.S. in Molecular and Human Genetics from BHU, India. During her PhD, at the interface of cell and developmental biology at NCBS, Bangalore, India, Anupama discovered the involvement of a novel endocytic pathway in Wingless (Wnt) internalization and signaling. While deciphering the cellular events that modulate Wnt signaling, she was fascinated by the convergence of cell fate signals with pathways involved in anabolic growth. In the Greco lab, Anupama plans to explore the principles of growth and homeostasis underlying tolerance to mutations in normal tissue.
