Felwa Alarwan

Master's, Mechanical Engineering and Applied Mechanics

Felwa is a second-year MEAM Master’s student, holding a B.Sc. in Mechanical Engineering from Alfaisal University in Riyadh. During her undergraduate studies, Felwa interned at Bechtel Corporation, Saudi Aramco, and the Saudi Industrial Development Fund. She also led Alfaisal University’s Shell Eco Marathon team, tutored several courses in Physics and Mathematics, and served as the leader of the Academics team in the Engineering Student Association. Being the only female in her Mechanical Engineering batch inspired Felwa to become one of the founding board members of the first Saudi Women Engineers Society. Additionally, she holds the position of Vice President at Wathba, a Saudi youth community that enables and matches youth with qualified mentors. Felwa worked at NEOM, managing water projects for two years and is currently on a scholarship to pursue graduate studies in the technological advancements of renewable energy and water sustainability. Her interests in education, sustainability, and science drive her to pursue interdisciplinary research opportunities generally, and in fluid mechanics specifically, at UPenn.

Rehan Kumar

Master's, Mechanical Engineering and Applied Mechanics

Rehan Kumar is a master's student in Mechanical Engineering and Applied Mechanics at the University of Pennsylvania. His academic excellence and commitment to innovation have earned him highest honors in his undergraduate studies, and he continues to drive progress in the field of mechanical engineering. With his strong background in thermal systems and heat transfer equipment design, Rehan developed a novel water cum air-cooled condenser for tropical climates that harvests water from the evaporator, resulting in a 5% increase in electrical efficiency. He explores heat transfer associated with salt crystal formation from evaporation of saline droplets on superhydrophobic surfaces in the McBride Lab. Currently, he is expanding his expertise in micro- and nano-fabrication techniques at the Quattrone Nanofabrication Facility, mastering various etching and deposition tools to create diverse micro- and nano-textures with tailored surface morphologies and wetting properties, further enhancing his research capabilities. Proficient in a range of computer-aided engineering tools, Rehan is driven to innovate sustainable solutions for real-world challenges.

Auriani F. Gómez Cintrón

'NSF Research Experience for Undergraduates' Intern, General Microbiology

Auriani F. Gómez Cintrón, a sophomore student at the University of Puerto Rico in Humacao, is currently pursuing a General Microbiology degree. Since a young age, she has been captivated by the field of science and has always dreamt of building a career in STEM. Throughout her academic journey, she has developed a deep passion for research, particularly in the realm of clinical research. By shadowing doctors and gaining hands-on experience in surgical and implant procedures, her interest in STEM and clinical research has only grown stronger. From the very beginning of her college experience, Auriani actively sought out opportunities to immerse herself in the world of scientific inquiry. She has even ventured into the chemistry department at her university, collaborating with Dr. Ezio Fasoli on chemical sensors. In the summer of 2024, she joined McBride's lab at the University of Pennsylvania, where she is currently focused on developing a standard operating procedure for detecting environmental microplastics using fluorescence microscopy. These experiences have ignited her enthusiasm for exploring further opportunities in the fields of microbiology and biochemistry, which are the central pillars of her academic and professional aspirations.
