Areas of Research Interest

Cartilage tissue engineering, regenerative medicine, osteoarthritis, drug delivery


Andy was first introduced to tissue engineering at Vanderbilt, where he worked with Dr. Hak-joon Sung to characterize the maturation of iPSC-derived cardiomyocytes using synthetic biomaterials. Through his work on the pathologies of the cardiovascular system, he developed an interest in disease characterization and reparative strategies at the cellular level. Andy first joined CEL at Columbia in the summer of 2015 and worked on a tissue engineered synovium model of inflammation in osteoarthritis progression. He came back in the fall of 2017 as a MS/PhD student and is now researching methods for sustained drug delivery in post-op joints to prevent arthrofibrosis. In his free time, Andy enjoys seeking out new cafes and eateries, and spends time outdoors playing tennis or running.
