DESCRIPTION:Application-guided design multifunctional mixed ionic-electroni
 c conductive co-polymers and polymer composites\n\nIn this talk\, I will s
 hare recent progress from my research group on designing conjugated polyme
 rs for iono-electronic devices. Such devices are key to the next generatio
 n of "smart" electronics for healthcare and consumer applications. Our res
 earch is aimed at addressing the unique demands of these devices\, which r
 equire a combination of mechanical flexibility\, stability in variable env
 ironments\, reliable signal processing\, and adaptability to execute speci
 fic functions. These requirements make iono-electronic materials—where a
  semiconductor responds to ionic signals with detectable changes in electr
 onic\, optical\, or mechanical properties—especially promising candidate
 s. My group\, the Laboratory of Organic Materials for Smart Electronics (O
 MSE Lab)\, is particularly interested in developing conjugated polymers th
 at can overcome the primary challenge in this field: balancing ionic perme
 ability with efficient electronic charge transport to create high-performa
 nce materials. In this presentation\, I will discuss how we achieve this b
 alance through molecular tuning of semiconductors\, employing techniques l
 ike co-polymerization and composite formation to build a diverse library o
 f mixed conductors. This approach has opened doors to applications ranging
  from fast-switching electrochemical transistors to highly accurate artifi
 cial synapses. Additionally\, I will share how we systematically attach po
 lar side groups to proven electron conductors to evaluate and enhance both
  ionic and electronic conduction\, which has proven crucial for optimizing
  device performance and expanding their application potential. Our ongoing
  efforts demonstrate how these materials can contribute to a new era of fu
 nctional\, adaptable electronics suitable for diverse and demanding enviro
 nments.\n \n\nBio: Aristide Gumyusenge is an assistant professor in the De
 partment Materials Science and Engineering at the Massachusetts Institute 
 of Technology. He received a B.S. in chemistry from Wofford College in 201
 5 and a Ph.D. in chemistry from Purdue University. Before joining DMSE\, G
 umyusenge was a postdoctoral fellow of the Geballe Lab for Advanced Materi
 als at Stanford University.\n\nAt MIT\, Gumyusenge’s research group\, OM
 SE Lab\, focuses on developing novel organic semiconducting materials and 
 using them to build organic electronic devices and body-machine interfaces
 . Through polymer design\, novel processing strategies\, large-area manufa
 cturing of electronic devices\, he’s interested in relating molecular de
 sign to device performance\, especially transistor devices that can mimic 
 and interface with biological systems.
