It is with a heavy heart that I reflect on the remarkable life and career of Dr. Lisa Emerson, who died from natural causes in September 2024. Lisa was an extraordinary young scientist, mentee, and friend who left an indelible mark on the lives of those she touched. I had the privilege of serving as Lisa’s graduate supervisor for four years, during which time she made remarkable contributions to both her personal growth and the broader research community.

Despite the brevity of her career, Lisa’s achievements and contributions to science were substantial and far-reaching. She authored twelve publications, including six as the first author. Her groundbreaking research on extracellular vesicles and their role in immunity against Salmonella infections garnered significant attention, leading to invitations to present at prestigious conferences such as the American Society for Microbiology and the International Society for Extracellular Vesicles. At the latter’s conference in France, her presentation was so impactful that the director quoted her during the closing remarks, and she was awarded a scholarship for her outstanding work.

While pursuing her Ph.D., Lisa received the highly competitive TL1 Predoctoral Trainee Grant from the University of Florida Clinical and Translational Science Institute. Through this grant, she developed a project focused on isolating and analyzing diverse Salmonella strains from wastewater, while also investigating novel exosome-derived vaccine strategies. The TL1 grant provided her with opportunities to further her research and participate in professional development events that honed her scientific and leadership skills.

Lisa shared her passion for science through mentorship and public outreach. She guided many students, several of whom went on to win awards and pursue advanced degrees. Her dedication to education was recognized in 2020 when she received the University of Florida’s Graduate Teaching Assistant Award. To help foster an appreciation in science in children and the general public, Emerson participated in outreach projects such as “Skype a Scientist” and “Scientist in Every Florida School.”

When the COVID-19 pandemic struck, Lisa went above and beyond by volunteering to transport patient samples, demonstrating her unwavering commitment to public health and her community. Beyond her scientific achievements, Lisa was deeply involved with the Humane Society, fostering and adopting animals—a testament to her compassionate and selfless nature.

After earning her Ph.D. from the University of Florida, Lisa continued to excel, securing a postdoctoral associate position at Emory University. In early 2024, she achieved her career goal of becoming an ORISE Postdoctoral Fellow at the Centers for Disease Control and Prevention (CDC), expanding her impact on public health research with the employer she had long aspired to work for.

Lisa’s resilience, enthusiasm, and dedication were an inspiration to everyone who knew her. She faced every challenge with grace, and her joy for life was evident in everything she did—whether mentoring students, volunteering, or conducting research. Her final words to me were filled with excitement for the future, a reflection of her boundless optimism and passion.

Lisa was an extraordinary scientist, a cherished friend, and an inspiration to all who had the privilege of knowing her. Her legacy will continue to live on in the many lives she touched, both in and out of the lab.

As a tribute to Lisa, the Lisa Emerson Memorial Scholarship Endowment in Microbiology has been established at the University of Florida. This annual scholarship will provide essential funding to graduate students pursuing their Ph.D. in microbiology and planning career in public health, helping to foster the same passion and dedication that Lisa embodied.
