Things are heating up for advocacy group Indy Women in Tech. This week it announced that its inaugural Indy Women in Tech Summit Sept. 5 will feature keynote speaker Mae Jemison, the first African-American women in space and founder and president of the Jemison Group and BioSentient Corp. She’ll speak to more than 350 local and national tech leaders on her “experiences and obstacles in the science and technology” sectors, the group said, “as well as what needs to be done today to redefine Indy’s tech community.” Also this week Ivy Tech Community College announced that its IvyWorks program, aimed at helping adults earn tech-sector credentials, will start classes Aug. 21. Indy Women in Tech provided a grant to support women in the program. And on Aug. 17, the inaugural “Ignite Your Superpower” STEM day, which targets middle-school girls, will take place at the University of Indianapolis. Indy Women in Tech partnered with Conner Prairie and Women & Hi Tech to put on the program.
