About Math Day at The Beach
This annual event was started in 2000 by the Department of Mathematics and Statistics under the directorship of Dr. Kent Merryfield, a charismatic leader with unparalleled expertise in high-school math competitions, and ran uninterrupted until Dr. Merryfield's untimely death in November of 2018.
In March 2019, the 20th Math Day at The Beach took place under the new directorship of Dr. Olga Korosteleva. Then the pandemic placed this event on hold for two years. The event returned on March 12, 2022, and has been held since.
