I am extremely grateful for all the support over the past 12 years since the beginning of this journey. I am so lucky to have the like-friend like-family colleagues, staff & students at IOE & UM. Special thanks go to my family & especially the cute kids keeping us entertained :)

[Ruiwei Jiang @RuiweiJ]

Congrats and thanks, Dr. @haoming_shen! It has been such a fun ride!! Many thanks to @shicongforever @jonxlee @SiqianShen @yafeng_yin serving on Haoming's dissertation committee.

WOW. "Teachers assume they are smart, hard-working & high-achieving, which can boost the grades of even academically mediocre AsianAm students." Q: How many biased teachers do we need to promote so many undeserving AsianAm students? #StopAsianHate

[Columbia University @Columbia]

“Asian American students who have earned admission to Harvard are smart, promising, and have no doubt worked very hard. But in ways . . . they may have also benefited from their racial status long before they applied,” writes sociology Professor @JLeeSoc. https://t.co/VR5JkgsWcV

Congrats, @haoming_shen! The paper (https://t.co/JJ1WdbGYgO) provides conditions under which a pessimistic/optimistic chance constraint yields a *convex* feasible region. Thx to @INFORMS @InformsOS for recognition!

[Ruiwei Jiang @RuiweiJ]

Glad to share my 1st paper with @haoming_shen, newly published online by Math. Program. @math_opt An interesting technical result: a complete description of the convex hull of a mixed-integer set, arising from a "shifted" submodular function. @UMIOE

Ambiguous chance constraints may produce *convex* feasible regions if we choose a different reference distribution than empirical. Super happy to work on this with @haoming_shen @UMIOE
