`
`I received my Ph.D. degree in Electrical Engineering from the University of Minnesota in December 2003. My
`advisor was Professor David J. Lilja. The focus of my Ph.D. thesis was microarchitecture and statistically-based
`simulation methodology and analysis.
`
`Between 2004 and 2009, I worked at Freescale Semiconductor (formerly Motorola's semiconductor division,
`now part of NXP) designing microprocessors and doing performance analysis.
`
`I got my law degree from University of Texas School of Law in 2012.
`
`Between 2012 and 2019, I worked at Dechert LLP as patent litigator, where I was part of three trial teams that
`obtained jury verdicts in Marshall, TX. (We went 2-1.)
`
`I am currently working as a term law clerk on all patent cases for the Honorable Alan D Albright in the Waco
`division of the Western District of Texas.
