overview

My primary research interests are in design optimization for additive manufacturing, multiscale methods, and computational mechanics. Currently, my research group is actively working on fast process modeling and topology optimization for metal additive manufacturing.

I joined University of Pittsburgh in 2008 as assistant professor and was promoted to associate professor in 2014 and to full professor in 2019. I am also directing the ANSYS Additive Manufacturing Research Laboratory at Pitt, which houses several of the most advanced metal 3D printers including the EOS DMLS, Optomec LENS, and ExOne binder jetting.

I did my undergraduate study at UC Berkeley and master's study at MIT. I obtained my Ph.D. from UC Berkeley under the supervision of Shaofan Li and Steve Glaser. I also conducted postdoctoral research with Wing Kam Liu at Northwestern University.

My research has been supported by NASA, DOD, DOE, NSF, America Makes, ANSYS, etc. I am collaborating with the industry extensively in my computational research for additive manufacturing through the MOST-AM Consortium, which I founded in 2016 and now has 30+ member companies and research labs.

I received the NSF BRIGE award in 2009, the Board of Visitors Faculty Award from my engineering school in 2016, and the Carnegie Science Award in 2018.
