Brief Bio:
Dr. Kiril Streletzky (a.k.a. Dr. S) is an associate professor of Physics and a strong believer in the exceptional educational value of undergraduate research. He has mentored 60+ undergraduates in soft matter research through independent studies, honors theses, McNair projects, and summer research projects in his state-of-the-art light scattering lab. These efforts, supported by $700k in external and internal funding, have led to 12 peer-reviewed papers coauthored by 16 undergraduates (two more currently in preparation).

Recently, Dr. S has expanded his mentoring role as the PI of CSU's NSF-supported Research Experience for Undergraduates (REU) Site: "Synthesis, Assembly, and Characterization of Soft Matter Systems" which each summer guides cohorts of undergraduates through the research enterprise by immersing them in a 10-week mentored research experience.

Beyond mentoring his own undergraduate researchers, Dr. S also has a unique role in training the CSU physics cohort at large as the faculty advisor to the CSU chapter of the Society of Physics Students (SPS), a position he has held since 2005. Dr. S also participates in training of CSU STEM students as a faculty advisor to the Choose Ohio First program in the lower division Success in Math track (since 2017) and the upper division Research/Outreach track (since 2018). In these roles, Dr. S supported numerous undergraduate researchers by developing a student seminar series, chaperoning students to regional/national conferences, organizing student conferences, and promoting research opportunities. He also served for 6 years as an elected member of the National SPS Council, where he advocated for a greater emphasis on undergraduate research nationwide.

Dr. Streletzky holds a BS Physics degree from the Moscow Institute of Physics and Technology and a PhD in Physics from Worcester Polytechnic Institute.
