The executive board is comprised of STEM professionals who share a vision of connecting scientists of all backgrounds and interests. ADSE executive board positions will be open to previous leaders of local chapters. 


    Steven Lopez, Ph.D.

    Chairman of the Board

    Assistant Professor of Chemistry and Chemical Biology

    Northeastern University

    Steven is an ADSE co-founder and the current Chair of the Board of Directors of ADSE. He received his B.S. in Chemistry in 2010 from New York University and his PhD in organic chemistry in 2015 from the University of California, Los Angeles. He is currently an assistant professor of chemistry at Northeastern University and the faculty advisor for the ADSE@NU chapter.


    The Lopez lab focuses on computational organic photochemistry and materials chemistry. His group is funded by the Office of Naval Research on a $500,000 Multi University Research Initiative (MURI) grant, National Science Foundation ($600,000) to use computational chemistry and machine learning techniques to design catalysts for organic photoredox reactions, and the Massachusetts Life Science Foundation ($750,000) to identify non-invasive alternatives to chemotherapy for site-specific cancer treatments.

    Osvaldo Guttierez, Ph.D.

    Board Member

    Associate Professor of Chemistry

    Texas A&M University

    Osvaldo was born in Mexico and raised in Sacramento, California. He attended Sacramento City College and transferred to UCLA in 2006 where he worked as an undergraduate at the laboratories of Prof. Houk where his research focused on the use of quantum mechanical calculations to study organocatalysis. He obtained his B.S./M.S. in 2009 and completed his Ph.D. in 2012 (UC Davis) under the guidance of Prof. Tantillo. From 2012-2016 he worked as a postdoc with Prof. Kozlowski at the University of Pennsylvania where he used computational and experimental tools to study transition metal-catalyzed processes. In 2016 he started his independent position at the University of Maryland College Park as an Assistant Professor, and then promoted to Associate Professor in Summer 2021. In the Fall 2021, he moved to Texas A&M University where his research combined computational and experimental approaches to advance our understanding of iron- and photo-catalyzed reaction mechanisms. In addition to research interests, Osvaldo is involved in a series of initiatives to increase diversity in STEM including serving as president of the Alliance for Diversity in Science and Engineering (ADSE) and organizer of the annual Young Researchers Conference (YRC) and Breaking Barriers Through Chemistry (BBTC).
