Dr. Kate Mansfield

Job Titles:
  • Biology
  • Marine Scientist
Dr. Kate Mansfield is a marine scientist and sea turtle biologist. Her research focuses on sea turtle biology, ecology, behavior, management, and conservation. Using various census and telemetry methods, Dr. Mansfield's research interests include sea turtle and other marine vertebrate movements, migration, and habitat utilization. Dr. Mansfield's recent projects include testing and deploying small-scale, solar-powered satellite tags on young, oceanic stage sea turtles with the goal of describing early sea turtle dispersal and habitat use. Dr. Mansfield's lab and field sites include the UCF Marine Turtle Research Group's (MTRG) long-term nesting beach and coastal juvenile research programs. The UCF MTRG has monitored beaches within and adjacent to the Archie Carr National Wildlife Refuge for many decades, focusing on the reproductive biology and population trends of Atlantic sea turtles. In addition to this beach program, MTRG's in-water netting program has monitored coastal (neritic) juvenile sea turtles in the Indian River Lagoon for over three decades. Combining these programs with Dr. Mansfield's oceanic juvenile tracking work, the MTRG provides a whole life history approach to understanding the biology, ecology, and conservation needs of Atlantic sea turtles.

Kay Israel


Mariana Sorroza

Mariana is double-majoring in Mechanical Engineering and International and Global Studies. She has expressed that Engineering has always been a huge interest of hers which is one of her biggest reasons for coming to UCF. As a member of the EXCEL program, she has received a lot of guidance as a female entering a STEM field and feels very fortunate to be able to pay that back by providing guidance to others through participating in the GEMS Mentoring program as a mentor the last two years. As a GEMS mentor, Mariana strived to remind her mentees that even though STEM can be challenging, it is also very rewarding and they are more than capable! She encourages students to push through the difficulties and to remember that even though being a student (especially a female) in STEM can be rough, they are tough! EXCEL has also helped her with networking, such as leading her to participate in Fairways to Leadership, where she learned how to play golf and gained additional leadership skills. Through her relationships with those leading the EXCEL program, she received assistance to become an ambassador on the President's Leadership Council and on getting an internship with the Minority Serving Institution Internship Program. From 2021-2022, she supported the National Nuclear Security's Administration Office of Nuclear Smuggling Detection and Deterrence and she is currently supporting the Office of Radiological Security; these are both offices that do work to protect people from nuclear and radiological threats both domestically and internationally. Mariana has additional involvement such as being a campus ambassador, a STEM ambassador, serving on the student code of conduct board, and volunteering at a local animal shelter. She hopes to continue contributing to EXCEL and expresses being immensely grateful for the positive impacts this program has had and continues to have on her life and career!

Mary Kate Wilkerson

Job Titles:
  • STEM Engagement Coordinator, ISTEM

Michael Scully

Michael received his Bachelor of Science in Mathematics from the University of Scranton in 2011; he received his Masters of Science in Pure Mathematics, with Distinction, from DePaul University in 2020; he is currently in his third year of the Pure Math PhD Program at UCF, with an interest in Discrete Mathematics. From 2011 through 2021, Michael worked as a quantitative analyst for several Banks (ING, USAA, BMO, Citizens Bank), where he specialized in risk management; in particular, holistically managing a bank across risk factors (Market, Credit, Liquidity and Interest Rate). In his spare time, Michael has an artistic passion - painting with acrylics and writing poetry; and occasionally, will do stand-up comedy. If Michael is not being artistic or working on his math research, you will likely find him golfing!

Moses Hinrichsen

Moses Hinrichsen is studying Aerospace Engineering. He is a second year EXCEL student, and lived in the LLC during his freshman year. He has been very happy to make new friends through the program, and opportunities to advance my educational and professional abilities.

Rebecca Vollmann

Congratulations to the 2018-2019 Black Faculty and Staff Association ‘Mentee of the Year' Award Winner, Rebecca Vollmann! Rebecca has been a dedicated member of the UCF EXCEL program since she started at UCF in 2016. During her second year at UCF, Rebecca began mentoring women entering the EXCEL program and has aided in increasing the retention rates of women in the STEM disciplines. Along with these achievements, Rebecca's mentorship in the WISE program at UCF has set her apart from other students and led to her nomination for the BFSA ‘Mentee of the Year' Award. Rebecca sets challenging goals for herself with the help of her mentors and this quality has helped her to truly excel at UCF. Every opportunity Rebecca takes at UCF has allowed for her to partake in even greater opportunities off-campus. She attended the Empowering Women Summit hosted by Mitsubishi Hitachi Power Systems, where the GEMS program received a kind donation. Rebecca was also an invited guest to a VIP breakfast hosted for the United Launch Alliance CEO, Mr. Bruno, and was also invited to be a guest at a luncheon for Dr. Nair, the Deputy Director for Basic Research within the Office of the Secretary of Defense. Rebecca's invitations to these events are a reflection of her hard work within her major and what makes her an excellent STEM representative at UCF. Along with the many opportunities she is engaged in with her major, Rebecca also enjoys participating in volunteer opportunities, such as Habitat for Humanity. Congratulations on the award, Rebecca!
