News/Blog – Shashaani Research Group

Apr 24: The group had a good night at the 2024 ISE CA Anderson Awards.

Ha received the ISE Distinguished Dissertation Award, which recognizes recent PhD graduates who have written original, innovative dissertations that reflect outstanding technical contributions and are likely to have significant scientific and societal impact! He will be the department’s nominee for the IISE Pritsker Dissertation Award and/or INFORMS Dantzig Dissertation Award. (Jeon-Ha’s friend, teammate and basketball buddy) received the award on Ha’s behalf as he was traveling. Congratulations Yunsoo!!

Shashaani received the ISE Faculty Scholar Award, which recognizes current ISE (tenure track) assistant and associate professors for excellence in research, teaching, and service over the past three calendar years and the potential for becoming a University Faculty Scholar.

Apr 24: Shashaani and Houser celebrating last session of Simulation Modeling class! Students are now to work on their final project–simulating a made-to-order Mexican food restaurant. Can simulations helps us identify what is the bottleneck in Chipotle queue? Good luck students and looking forward to your simulation!!

PS: Thank you TAs Ethan Houser and Nicole Felice for all your help!
