As an organic chemist, Dr. Leila Hojabri synthesizes biomaterials from agricultural sources – making products that are much “greener” than those from petroleum-based materials.

Dr. Hojabri is excited about the great potential of these materials to help make a more environmentally sustainable society. She would like to further explore synthesizing lubricants and waxes from lipid.

Dr. Hojabri is delighted to be able to work in such satisfying collaboration with other researchers in the group, and challenges herself to stay as up-to-date as possible on developments in her field in order to bring as much knowledge as possible to these collaborations. She really enjoys the opportunity to exchange information with the other researchers, and finds the process helps her to understand and appreciate her colleagues’ fields of inquiry.

With a firm commitment to both the environmental sciences and interdisciplinary approaches, Dr. Hojabri is excited, too, by the great potential for this kind of broad-reaching, world-changing research at Trent.

Coming from two years at the University of Alberta in Edmonton, Dr. Hojabri finds Peterborough a green, beautiful and relatively peaceful place. As of her first fall in Ontario, she even likes the weather.

After amazing visits to Niagara Falls, Jasper and Banff, Leila and her family crave more travel. Next up: la belle province, Quebec.


AliAli Mahdevari
Tehran, Iran
Lab Manager
B.Sc. (Chemical engineering) Azad University of Tehran

Peering into his microscope, Ali Mahdevari sees evidence of the way biomaterials behave as temperatures change. Ali prepares samples and keeps lab equipment calibrated
and maintained, ready to measure for key indicators like viscosity and shear rates; mechanical properties like modulus, creep, and coefficient of expansion; textural properties like hardness, spreadability, extrudability, and stickiness.

Ali enjoys a challenge. To him, new problems are just a way to finding new solutions, and to getting to know his equipment even better. Like any Lab Tech, Ali appreciates his colleagues’ collaboration in keeping the instruments and lab clean.

New to Peterborough, Ali is impressed by the natural beauty of the university campus and the Peterborough area. Not to be outshined by natural splendor, members of the community impress Ali and his family with their own warmth and kindness.

Ali tells us he enjoys spending time with his spouse, and we believe him. Their first child is on its way this year!

In her down time, Jiaqing enjoys reading gentle, finely crafted and invigorating novels; swimming; and watching rousing, fast-paced movies. She has a special penchant for popcorn.


CarolynCarolyn Payne
Peterborough, Ontario, Canada
Laboratory Technician
BSc (Chemistry/Economics), Trent University, Peterborough, Ontario, Canada

As a local native of Peterborough and of Trent University, Carolyn brings many years of experience to the Biomaterials Group. She is a retired chemist from a local industry but has decided to keep her foot in the lab, so to speak. Carolyn helps keep the labs in good condition, performs testing, calibrates equipment, and trains the budding chemists.

She especially enjoys the multi-cultural experience and young people in the group.

In her spare time in the winter, you can find her on the ice playing hockey and in the summer you can find her paddling a kayak up a quiet stream.

RichardDr. Richard Hughes
Peterborough, Ontario
Research Associate (Analytical)
M.Sc. (Trent) Physical Chemistry
Ph.D. (Queen's) Physical Chemistry

Dr. Richard Hughes believes that eight heads tackling a problem are much better than one. While he might know a lot more about physical chemistry and number crunching than he does about animal anatomy, Dr. Hughes does know that he deeply enjoys being part of a dynamic team.

As a Trent graduate (M.Sc., 1980), Dr. Hughes is especially pleased to see developments in biomaterials occurring here, at an institution with such commitment to both environmental sciences and interdisciplinary approaches. In his work on the biomaterials team, Dr. Hughes helps fellow team members by using mass spectrometry to better understand the structure of compounds of interest. Dr. Hughes is co-author of one of the enduring authorities on Ion Trap Mass Spectrometry.

Being part of a team where each team member gets support, advice and help from the others makes work on the biomaterials team feel like a microcosm of the way things should be headed. And how fitting to have such a sustainable, supportive work structure when working so intensely in a field so tied to environmental sustainability!

Believing that any move away from petroleum is a step in the right direction, Dr. Hughes is excited to contribute his knowledge of Physical Chemistry to help establishing future research paths for the team.

Outside of work, you can find Dr. Hughes online, sometimes hopping so far down a chain of web links that he happily loses sight of why he started. He also enjoys catching up with his grown children, cycling on the extensive system of local bike paths, and enjoying favourite movies.

DerickLila Derick Ajumni
Bamenda, Cameroon
Graduate Student

BSc (Geology), Université de Yaoundé I - Yaoundé, Cameroon
MSc-Maitrise (Geology),  Université de Yaoundé I   -Yaoundé. Cameroon
Master (Environmental Science & Policy), Clark University, Massachusetts, United States

With a background in natural sciences and a repertoire of interdisciplinary study on two continents; Derick believes that the sustainable economic growth of any society is powered by a clean environment, in which water quality, health and eco-social values are indispensable criteria for success. He strives to use approaches that differ from the norm to confront the complex issues of waste management, while providing alternative financially feasible options.

Derick’s interest in the Biomaterials program flares as the program strives to synthesize more environmentally 'friendly' polymers for use in the manufacture of lubricants. With an itch to solve issues with plastic waste and pollutants, getting involved in this program couldn't be but a real advantage.

The program presses to completely merge the thin line between corporate R&D and Academic Research with the aim to synthesize products that are further developed into 'green' commodities for the consumer stream. Products that don’t resist the recycling capabilities of our natural environment. He got involved in the research group because of its multidisciplinary nature.

The group has talents from Physics and Astrophysics, Chemistry (Organic & Inorganic), Engineering, Sustainability, and Environmental Sciences. With the flow of information and ideas within such a group, ideas and feedback gets passed along and various perspectives are reviewed.

When not purposefully hurrying through the hallways of Trent University’s Graduate Building from one end to the other, Derick enjoys playing soccer, watching Movies, and hiking in warm weather.
