I am an Associate Professor of Biochemistry & Biology and an elected Fellow of the American Academy of Allergy, Asthma & Immunology (FAAAAI). My work sits at the intersection of environmental exposures, immunology, and respiratory health equity. I lead mentee-integrated projects that analyze how bioaerosols, indoor dust, and chemical/physical pollutants shape immune and physiological responses—work advanced through collaborations and funded studies spanning CDC-, NIH-, HUD-supported efforts and post-disaster research in Puerto Rico. I direct student-centered research via the Educational Biomarker Discovery Lab (EBDL) and the RIPLRT Institute, and I actively publish and present in exposure science, aerobiology, and immunology.

Across more than a decade in higher education, I’ve taught graduate and undergraduate courses including Biochemistry, Molecular Genetics, Immunology, Microbiology, Advanced Physiology, Biostatistics/Computational Biology–adjacent modules, and Science & Society. My training includes a Ph.D. in Microbiology (UPR–MSC), a postdoctoral fellowship in Environmental Health Sciences (Johns Hopkins), an ASM Science Teaching Fellowship, and extensive coursework in data science, genomics/bioinformatics, systems biology, and AI.

My teaching philosophy is to build inclusive, psychologically safe, and transformative learning environments where students feel seen, supported, and challenged. I normalize productive mistakes, promote values-driven mentorship, and help students venture beyond their comfort zones to master biochemistry, microbiology, immunology, genetics, computational methods, and public health with real-world relevance.

Another Great Session

Dr Felix is so helpful with bioinformatics topics. He was able to give me real world examples in laymen’s terms so I could feel confident in the subject matter and complete my assignments. I recommend him to anyone seeking a tutor.

Amazing!!!

Felix is so patient and knowledgeable and really does his best to help you learn and understand the concepts. He's not someone who will give you the answer straightaway but it is definitely for the better since it helps YOU to understand the content and make the connections with his guidance, and the content will stick around in your brain longer. After having him teach me about the various pathways (glycolysis, gluconeogenesis, PPP, TCA, etc.) I managed to raise my exam score by 30 points between exams! Would definitely recommend taking lessons with Felix :D

Beyond helpful!

Dr Felix is so nice and understanding. I came into the session very frustrated after a week of struggling with a bioinformatics assignment on my own and left feeling much more confident in the content of my class. After a two hour session, he had helped me understand not only the “how” but the “why” of the assignment. I would recommend him to anyone in need of help.

I enjoyed learning with Felix R!

Felix R is unquestionably well-versed in crafting persuasive proposals with a strong focus on constructing a compelling narrative. Our session started with his question: What are your research goals, and what do you hope to achieve through this endeavor? and that kept me thinking and revisiting many of my methods.

Amazing teacher

Dr. Rivera-Mariani was extremely knowledgeable about immunology and able to help me despite many other tutors feeling uncomfortable answering my questions. He had immediate responses to my questions and asked questions during the tutoring session to allow me to apply the information I learned. Dr. Rivera-Mariani also looked at the lecture slides I sent him prior to the tutoring session so he knew what I was working with. In the hour I spent with him I was able to learn and clarify what my class had be learning for 3 weeks as well as fill in the gaps despite my countless hours of reading. I will be booking future tutoring session and I highly recommend Dr. Rivera-Mariani.
