  • Daniela Vargas Robles

    Daniela Vargas Robles, PhD

    Postdoctoral Fellow

    Daniela completed her B.S. in Biology at the Universidad de Los Andes, Venezuela, and her Ph.D y Microbiology at the University of Puerto Rico. Daniela is interested in understanding the balanced relationship between a host and its microbiomes and studying what happens when this equilibrium is disrupted by practices of our lifestyle. In the lab, she works with the data that just came out from a particular experiment or project. She first does the data cleaning and has it ready to process it. Then, she analyzes it and generates plots and tables that help interpret biological phenomena. Daniela discusses and proposes different approaches to how to process and treat the data to extract the most relevant information. In her free time, she loves dancing, climbing, and doing outdoor activities.

  • Dylan C Hickey, BA

    Dylan C Hickey, BA

    Research Associate I

    Dylan earned his B.A. from the College of the Holy Cross while majoring in Biology. He was involved in HIV research as an undergraduate at the college. He is interested in how microbiome differences affect processes in the body, especially in those with IBD. In the lab, he processes samples from various studies as well as manages inventory to make sure all samples are sorted correctly. As a part of the DAIN study, Dylan helps to organize participant data and assure all timepoints are collected in the study. He is also involved in studies around microbiome changes in mothers with preeclampsia. Outside of work, Dylan loves going on his boat in Rhode Island, binging TV shows, and walking his dog.

  • John Solitro, MS

    John Solitro, MS

    PhD Candidate
    John completed his B.S. in Biochemistry and Molecular Biology at UMass Amherst and M.S. in Nutritional Biology at UC Davis. Currently, John is pursuing his Ph.D in Biomedical Sciences and has a strong passion for both basic and applied sciences. In his free time, he enjoys traveling, hiking, biking, playing recreational sports, and weightlifting.
     
    "My research interests are in ‘personalized nutrition’, omics technologies, and understanding the interactions between a host’s genetics, diet, microbiome, and immune system."
     
  • Lymarie M. Díaz-Díaz, PhD

    Lymarie M. Díaz-Díaz, PhD

    Postdoctoral Fellow

    Lymarie received her bachelor’s degree in Cellular and Molecular Biology at the University of Puerto Rico, Río Piedras Campus. At same institution, she completed her PhD in Biology where she described the microbial community associated with sea cucumbers (Holothuria glaberrima) undergoing intestinal regeneration and evaluated the impact of the microbiota during intestinal regeneration of this holothuroid. Meanwhile, she acted as a consultant to the DAIN project, where her roles ranged from informative material editor to social media content creator. Currently, she is integrated into our group as the Postdoctoral Associate and will oversee the effects of DAIN on microbial and molecular profiles of CD patients. 

    “Since I was a child, my grandmother taught me about the medicinal properties of food and herbs. I grew up thinking that I could cure people with the crops I plant. Indubitably, she inspired me to become a biomedical researcher, which I would plan to continue as post-doctoral fellow in Dr. Ana Maldonado-Contreras lab. In addition to planting, I am a passionate teacher/mentor, and I have multiple hobbies such as singing, salsa dancing, watching musicals and comedies, jewelry crafting, and traveling, among others.”
