Yuan (Alan) Qi

Research Interest

My research interest lies in machine learning, Bayesian statistics, and their applications in various scientific and engineering disciplines such as computational biology and computational materials science. I  address critical computational and statistical challenges associated with  massive data analysis, helping the study of complex biological, social, and synthetic systems. To this end, I design relational, sparse, and nonparametric Bayesian graphical models driven by various applications, and develop scalable Bayesian inference algorithms for these models.

Brief Bio

I obtained PhD from MIT in 2005 and worked as a postdoctoral researcher at MIT from 2005 to 2007. I joined Purdue university in 2007 and was tenured in 2013. I received the A. Richard Newton Breakthrough Research Award from Microsoft Research in 2008, the Interdisciplinary Award from Purdue University in 2010, and the NSF CAREER award in 2011.

To Applicants

If you are interested in joining my group and have passion in machine learning/statistics with a solid background in probability, linear algebra and/or optimization, welcome to contact me via email. Please attach your CV in your email.
