We bid farewell to star undergrad intern Jiahao Chen, who heads back to China this week. Jiahao gave a super wrap-up talk describing his work on directed alkene difunctionalization under the mentorship of Zhen. His research experience in the Engle lab marked his first time gaining exposure to transition metal catalysis research after previous experiences in radical chemistry with Prof. Jie Wu at Fudan University and in total synthesis and medicinal chemistry with Prof. Mingji Dai at Purdue University. Next up: studying for the GRE and getting ready for grad school applications. Thank for your hard work and great attitude, Jiahao! Thanks too to Zhen for great mentorship throughout the spring!
