Sher­win obtained a B.Sc. in Infor­ma­tion Tech­nol­o­gy Engi­neer­ing from Islam­ic Azad Uni­ver­si­ty (Zan­jan, Iran) and an M.Sc. in Cog­ni­tive Sci­ence (Mind, Brain and Edu­ca­tion) from the Insti­tute for Cog­ni­tive Sci­ence Stud­ies (Tehran, Iran). For his master’s the­sis, he devel­oped a bio­log­i­cal­ly plau­si­ble frame­work that com­bined spik­ing neur­al net­works with a neu­ral­ly inspired dif­fu­sion mod­el to inves­ti­gate lex­i­cal deci­sion mak­ing, link­ing neur­al fir­ing pat­terns to behav­ioral mea­sures such as response time and confidence.

He lat­er joined the Insti­tute for Research in Fun­da­men­tal Sci­ences (IPM, Tehran) to work on nov­el ker­nel meth­ods for sup­port vec­tor machines and con­tin­ued his research in com­pu­ta­tion­al mod­el­ing of deci­sion mak­ing at the Com­pu­ta­tion­al & Math­e­mat­i­cal Psy­chol­o­gy Lab of Shahid Beheshti Uni­ver­si­ty. Most recent­ly, he exam­ined rein­force­ment-learn­ing accounts of the Iowa Gam­bling Task, using sim­u­la­tions and para­me­ter-space-par­ti­tion­ing to test whether human choice pat­terns can be repro­duced by exist­ing mod­els. In 2025, Sher­win began his PhD at the O’BRAIN Lab, where he applies brain-inspired spik­ing neur­al net­works to study how binge-eat­ing dis­or­der alters con­nec­tiv­i­ty and tem­po­ral dynam­ics in reward and con­trol cir­cuits, and whether dis­tinct spa­tio-tem­po­ral acti­va­tion sig­na­tures can dif­fer­en­ti­ate BED from obe­si­ty and healthy controls.
