Prof. Rafik Naccache, PhD
Professor · Co-director, Centre for NanoScience Research (CeNSR)
Rafik Naccache is a Professor in the Department of Chemistry and Biochemistry at Concordia University and Co-director of the Centre for NanoScience Research (CeNSR). He previously held a Concordia University Research Chair (Tier 2) in Sustainable Multifunctional Nanomaterials (2021–2026).
He obtained his PhD in Chemistry at Concordia (2012), working on lanthanide-doped upconverting nanoparticles for imaging, and received the Distinguished Doctoral Dissertation Prize and the Governor General’s Gold Medal. He then completed NSERC postdoctoral training in nanobiophotonics at the Institut national de la recherche scientifique (INRS), developing terahertz sensing applications, before joining Concordia in December 2015 as a strategic hire in nanomedicinal chemistry. He has since been named a Concordia University Research Fellow and a Petro-Canada Young Innovator.
His group studies the fundamental properties of fluorescent carbon nanomaterials and hybrid nanosystems and applies them to biosensing and imaging, drug delivery, catalysis and clean energy. Before his academic career he spent a decade in pharmaceutical R&D at Merck Frosst (Merck & Co.), working on materials characterization and drug development, and he continues to consult for pharmaceutical companies.

Mitacs Postdoctoral Fellow
Dr. Haitham Shoman
Sensing & diagnostics
Bio
Haitham Shoman is a physician-scientist in translational medical technology and the founder and CEO of Qalam Health. Haitham earned an MD from Ain Shams University (Cairo), an MPH from Imperial College London as a Chevening Scholar, and an MSc in Health Policy and Management from Harvard University, and completed MIT’s program in Medical Device Design and Development. As a Vanier Canada Graduate Scholar, Haitham then completed a PhD in Experimental Surgery at McGill University. That career spans more than 20 years across academic surgery, global health and the medtech sector, including the World Health Organization, Harvard Medical School and Cambridge University Hospitals.
Research
Haitham works on precision medicine in surgical oncology. With clinical and research collaborators, the team is developing the Qudrapen, an AI-powered handheld probe that combines molecular imaging with machine learning to tell cancerous from healthy tissue during surgery. The work involves building a tissue spectral library, training machine-learning models and validating the technology against histopathology, with trials under way at the Montreal General Hospital. The aim is to give surgeons timely information to remove tumours precisely while sparing healthy tissue.

PhD Student
Camilo Garcia-Henao
Luminescence & materials
Bio
Camilo is a chemist whose early work focused on nanomaterials for environmental adsorption, reduction and oxidation processes. A keynote by Prof. John Capobianco on lanthanide ions changed his course, and he retrained as a spectroscopist. When he isn’t running syntheses, doing spectroscopy or deep in data analysis, he can usually be found in the pit at a rock show or playing guitar at home.
Research
Camilo develops X-ray-activated, lanthanide-doped persistent luminescence nanoparticles for optical sensing in situations where constant excitation is not feasible. He uses defect engineering to balance efficient luminescence against high trap-storage capacity, aiming for bright, long-lasting emission across a range of temperatures. By introducing defects systematically and evaluating them through rigorous spectroscopy and data analysis, his work seeks to explain how these structural changes drive persistent luminescence in lanthanide-doped fluoride nanoparticles.

PhD Student
Luis Páramo Serrano
Clean energy
Bio
Luis Alfonso Páramo Serrano holds a BSc in Nanotechnology Engineering and an MSc in Nanotechnology from the Autonomous University of Querétaro, Mexico. He is particularly interested in controlling the synthesis and optical properties of CuInSe₂-based quantum dots.

Research
Luis develops copper-based chalcogenide nanomaterials for solar energy conversion. He studies the synthesis of CuInSe₂ nanoparticles, with emphasis on controlling their composition, structure and optical properties. In parallel, he develops new mechanochemically prepared precursors and examines how their structure influences reactivity and, in turn, nanomaterial formation.

PhD Student
Momodou Jallow
Sensing
Bio
Momodou completed an MSc in Chemistry at King Fahd University of Petroleum and Minerals, where he developed polymer–graphene oxide nanocomposites that inhibit shale hydration in water-based drilling fluids. His interests span carbon-based nanomaterials, surface functionalization, fluorescence sensing and environmental analysis. He is active in teaching, student mentorship and chemistry outreach, and his long-term goal is accessible, sustainable analytical technology for environmental monitoring, particularly for communities with limited resources.
Research
Momodou develops fluorescent carbon dots from renewable biomass for sensitive, selective detection of environmental pollutants. He studies how precursor composition and surface functionalization shape optical properties, fluorescence response and analyte recognition, with a focus on nutrient pollutants from agricultural runoff. The goal is a portable, low-cost fluorescence sensing platform that combines green chemistry, nanomaterials, analytical chemistry and portable instrumentation to support water-quality monitoring.

PhD Candidate (co-supervised with Dr. Louis Cuccia)
Gregory Amato
Clean energy
Bio
Gregory was born and raised in Laval, Quebec, and completed a BSc in Chemistry at McGill University. As an undergraduate, Gregory synthesized dithiophosphate ligands and their cobalt complexes with Dr. Bohle, and developed a tensile testing method for mussel byssal threads with Dr. Harrington. Outside the lab, Gregory enjoys miniature painting, trading card games and other hobbies that combine creativity and strategy.
Research
Gregory studies chiral materials and the links between chirality, magnetism and triboelectric charge transfer. The focus is the chiral-induced spin selectivity (CISS) effect, in which chiral materials interact preferentially with electrons of one spin orientation, and how it may influence charge transfer in triboelectric nanogenerators, devices that turn mechanical motion into electrical energy. Through materials synthesis, thin-film fabrication and electrical characterization, the project probes the role of electron spin in contact electrification.

MSc Student (Nanoscience & Nanotechnology; co-supervised with Dr. Sana Jahanshahi-Anbuhi)
Samuel “Stash” Wrobel
Sensing
Bio
Stash grew up on a sheep farm in Montana before his studies took him far from agriculture. He studied molecular neuroscience at the University of Montana and worked in a diagnostics laboratory, developing new testing methods for respiratory diseases and Neonatal Opioid Withdrawal Syndrome. After studying Spanish in Granada, Spain, he moved to Montréal for a master’s in Nanoscience and Nanotechnology. Outside the lab he plays tennis, mountain bikes, skis, and loves almost any outdoor activity.
Research
Exhaled volatile organic compounds (VOCs) can signal acute and chronic respiratory diseases. Stash is developing a non-invasive diagnostic: a photoluminescent carbon dot sensor, with the dots immobilized on paper and integrated into a wearable mask. Gaseous VOCs change the dots’ fluorescence in a measurable way, offering a route to earlier, more reliable diagnosis of lower respiratory infections and chronic pulmonary conditions.
