Javid Validashti
I am a senior lecturer in the Department of Mathematical Sciences at DePaul University in Chicago. I earned my Ph.D. in Mathematics at Purdue University in 2007 under the direction of Professor Bernd Ulrich. Prior to DePaul, I served as an Assistant Professor at Cleveland State University and held postdoctoral positions at the University of Kansas and the University of Illinois Urbana-Champaign. My research interests are in Commutative Algebra, Algebraic Geometry, and Combinatorics.

Teaching Experience
Throughout my academic journey, I have had the privilege of teaching a wide range of undergraduate and graduate courses at prominent universities, including Purdue University, the University of Kansas, the University of Illinois Urbana-Champaign, Cleveland State University, and currently at DePaul University. My teaching philosophy is anchored in the principles of critical thinking, inclusivity, and structured active learning. In recognition of my effective teaching, I was awarded the Distinguished Teaching Award in Mathematics at the University of Illinois Urbana-Champaign in 2014. Since joining DePaul University in 2018, my primary focus has been delivering high-quality lectures and ensuring accessibility in my classes. I have completed the DePaul Online Teaching Series (DOTS) program and have designed and offered several online courses, leveraging innovative instructional technologies to enhance student engagement and learning outcomes. In addition to my classroom teaching, I have been involved in various service and outreach activities. For instance, I served on the Discrete Mathematics Redesign Committee and collaborated with my colleagues to revamp the Discrete Mathematics curriculum. In addition, during the summer of 2019, I served as the lead instructor at the Actuarial Summer Academy, held at the Center for Risk Management in the Driehaus College of Business at DePaul. Furthermore, I had the privilege of delivering a series of lectures on Multiplicity Theory during the MSRI Graduate School's program on Commutative Algebra and its Interaction with Algebraic Geometry at the University of Notre Dame as part of the Thematic Program in Commutative Algebra and its Interaction with Algebraic Geometry in June 2019.
