Publications

Below is a list of publications, venues, and philosophy.

Publication Venues

My publication venues have ranged generally on the intersection of imaging & learning (PAMI,CVPR,ECCV) to control (ACC,CDC,TAC) to networks (Science, Nature, MTNS) to systems biology (TMI, BIBM).

PhD Publication Advice (For Students)

• Never let anonymous reviewers degrade your work. Its your idea, you know it best!

• You are fortunate if you have one good idea, and if lucky, two great ideas in a lifetime!

• Consider publications as a service.

• Balance learning and publishing (independent events)

• Follow your passion and not some metrics (citations, venue).

• Publication productivity does not necessarily equal quality (maybe the opposite?).

• Make mistakes, get rejected. At best, you learn. At worst, its a reason for beers.

• Honesty, kindness, and politeness are the best transactions. It also costs you nothing.

• Methods are developed by skills. Learn a skill, not just the method.

• Academia does not need to fit classic stereotypes, only if you allow it.
