Research
I work in probability theory (stochastic analysis, diffusion processes on Lie groups, random matrices, and free probability),
mathematical physics (YangMills theory, quantum information theory), and functional analysis
(functional inequalities, heat kernel analysis, holomorphic and subharmonic function spaces).
I am the organizer of the UCSD Probability Seminar and the UCSD Functional Analysis Seminar (20182019).
These are researchlevel seminars with largely outside speakers. If you are interested in speaking in either of these seminars, please contact me.
I am a Founding Faculty member of the Halicioğlu Data Science Institute.
I have 3 former PhD students:
 Natasha Blitvic (PhD, MIT, 2012) works in noncommutative probability and enumeratuve combinatorics. She was a Zorn postdoctoral fellow at Indiana University, and
is now Lecturer (tenuretrack Assistant Professor) at Lancaster University in the UK.
 David Zimmermann (PhD, UCSD, 2015) works on log Sobolev inequalities and random matrices. He was a Dickson Instructor at the University
of Chicago, and now works at Raytheon, in Los Angeles.
 Ching Wei Ho (PhD, UCSD, 2018) works on the SegalBargmann transform, free probability, and complex analysis. He is now a Zorn postdoctoral fellow at
Indiana University.
I have one current PhD candidate, Alice Chan, entering her fifth year. She works on the SegalBargmann transform on highdimensional Lie groups,
random matrix theory, and free probability.
