Vagan Tapaltsyan, DDS, PhD

A Berkeley resident since 2010, Dr. Tapaltsyan spent the first part of his childhood in Europe, attending a foreign language immersion preparatory school before moving to the US for high school. He went on to graduate Summa Cum Laude with a BS in Biology from the University of Central Oklahoma, where he was also a member of the sailing team. Continuing on his lifelong path of going West, Dr. Tapaltsyan moved to California for graduate studies and received both his DDS and PhD in Stem Cell and Regenerative Medicine from UCSF, where he currently holds the rank of Assistant Professor and is the Director of Evidence-Based Dentistry Program.

In addition to practicing dentistry and teaching, Dr. Tapaltsyan's research interests include understanding how dental stem cells develop and evolve, which can one day help us regenerate new teeth and bone. He has authored many research articles and book chapters on this subject and lectures internationally.
