Research Teaching Publications Awards & Grants


Dr. Aris Docoslis is a Professor in the Department of Chemical Engineering at Queen’s University and former NSERC Tier II Canada Research Chair in Colloids & Nanoscale Engineering (2003-2013). His research interests lie in the fields of Applied Colloid Science and Interfacial Engineering. His research is primarily experimental in nature and finds applications in Health (portable diagnostics), Environment (membrane separations, chemical detection of pollutants) and novel materials and manufacturing (graphene-based films and sensors).

Prof. Docoslis is also one of the inventors of a patented technology that has been commercialized by Spectra Plasmonics Inc., a Kingston-based start-up company. He is the author of over 80 peer-reviewed articles, 4 book chapters, co-inventor of 2 US patents, and the co-author of an international, 1 US, and 2 Canadian recent patent applications.


Research Interests

  • Development of novel chemical sensors and portable diagnostic devices
  • Graphene-based thin films, coatings, and membranes
  • Raman spectroscopy (SERS)
  • Filler/polymer nanocomposites
  • Nanoparticle electrokinetics; Synthesis of functional structures with nanometre-scale order


Training of Researchers

Professor Docoslis strives to ensure that students, postdoctoral associates, and research assistants in his group receive high quality training through mentoring, collaborations with industry, and participation in professional development activities (Conferences, Seminars, workshops, research networking). His hiring practices emphasize equity, diversity, and inclusion and encourage applications by historically underrepresented and equity-seeking groups.

Professor Docoslis has trained more than 25 Master’s students (MASc/Meng), 13 PhD students, 10 postdoctoral associates, and 5 research assistants/associates. He has also supervised the 4th year thesis or summer research work of over 35 undergraduate students. Most of his trainees work in cross-disciplinary research projects that involve joint collaborations with industry/government, or other academic partners.

Researchers in the Docoslis lab acquire technical expertise and skills desirable by the industrial, academic, and government sectors. These skills can be applied to the fields of, e.g., diagnostic devices, chemical sensors, electrochemistry, microfluidics, chemometrics, environmental remediation, graphene-based products and technologies, and polymer composites manufacturing. Such skills will make them employable in the medical diagnostics sector, by small/medium size companies seeking to enter new and emerging markets through the commercialization of smart sensors, lab-on-a-chip devices, spectroscopy instrumentation, or flexible electronics, or in environmental engineering and science. Past experience shows that HQP working directly with our industrial collaborators often end up as their employees.
