[Hamidreza Validi @ValidInequality]

I am excited to announce that I will be joining the IMSE department @TexasTech in Fall 2022! Many thanks to many @RiceEngineering, @OkStateIEM, and @lehigh_ise!

Special thanks to my postdoc and PhD advisors, Drs. Illya V. Hicks and @AustinLBuchanan, for all the support! #orms

Mr. @SecMullinDHS, as you step into your new position I ask you to provide particular consideration to the status of Iranian students and professionals in the United States who may be at risk of immigration complications due to Presidential Proclamations 10949 and 10998. Many of these individuals fled the Islamic Republic’s because they believe in freedom, democracy, and the values this country stands for. They are also contributing to the United States every day.

They arrived in this country legally, followed the rules, respect this country and its system of law and order and are among the most dedicated and accomplished contributors to American society. I ask that you and your department consider these factors, plus the personal and political risk many of these young people would face if sent back to the criminal regime in Iran.

America’s concerns for its national security and the threat posed by the Islamic regime to the homeland are entirely justified. To that end, my office stands ready to provide you and your colleagues with regime operatives, propaganda agents, and influence networks for investigation and removal from the United States.

Thank you for your consideration.

I had a great experience of using @Tim_Roughgarden’s book to cover the NP-completeness section of my Network Optimization course in Spring 2023. #orms

Huck will be missed at @Ttuimse! @TAMUISEN is super lucky to have you.

[David Huckleberry Gutman @DavidHGutman]

After 4 fantastic years at TTU, it’s time to move on. Today, I joined the faculty @TAMUISEN. I am grateful to my colleagues at TTU for their support and will be eternally indebted to my mentors, Bryan Norman and Tim Matis. Looking forward to the next chapter in College Station!

Thanks to @DIMACSCenter @DIMACSChallenge for posting my talk on the traveling salesman problem and the TSP work of the great David S. Johnson.

I am as ecstatic as I am surprised (and I'm VERY surprised) to announce that I have received an NSF CAREER Award! My five year project will seek to establish optimal rates for continuous optimization over Riemannian manifolds.

Enjoying @INFORMS2022 so much. Catching up with old friends, meeting new people, and learning recent research advances. I am especially thrilled to share this special moment with @PeterYunZhang for winning the #JFIG paper competition.

[Phebe Vayanos @phebe_vayanos]

.@aghaei_sina is on the academic job market this year! He does great work at the interface of optimization and machine learning and focused on issues of interpretability, fairness, and robustness. Check out his talk and session in a bit @INFORMS2022 !

[Jack Zhang @JackZha60493221]

I am excited to be presenting our work in @MShahmizad's political redistricting session at @INFORMS2022.

[Rice Engineering and Computing @RiceEngineering]

Congratulations to Prof. Illya Hicks, chair of the Dept. of Computational Applied Mathematics and Operations Research, on being elected vice president of education for @INFORMS!

If you're a professor or a student in STEM in a Western country, you probably know someone from the Sharif University of Technology in Iran. They might have be your students, peers, or friends.

That university is now under attack by the Islamic Republic.
