He completed his first 8 classes at School no. 11 Mihai Eminescu and secondary education at Ion Brătianu High School in Piteşti, and his undergrad and Ph.D. at Harvard University under the direction of Peter B. Kronheimer. His thesis topic was A spectrum valued TQFT from the Seiberg–Witten equations. His research interests span the areas of gauge theory, symplectic geometry, algebraic topology, and low-dimensional topology.
He is among the handful of recipients of the Clay Research Fellowship (2004–2008).
He has one of the best records ever in mathematical competitions:
- He holds the sole distinction of writing three perfect papers at the International Mathematical Olympiad: Toronto, Canada (1995); Bombay, India (1996); Mar del Plata, Argentina (1997).
- He placed in the top 5 on the William Lowell Putnam Mathematical Competition for college undergraduates in 1997, 1998, and 2000.
