Approach to graduate student supervision
I find that students need to realize that there is a broad spectrum of talents, that each has unique talents and one is more skilled in a given area than another, that while at an earlier stage in their lives there were pressures for conformity, now they should recognize the great values of diversity.
An important part of the teaching in a University occurs in the research laboratories where students undergo the transformation from assimilating knowledge to generating new knowledge. This transformation occurs under the guidance of the professor in whose laboratory the work is done. My approach to graduate student supervision is guided by the following premises:
- provide as much guidance and support as necessary, and as much independence as possible;
- challenge graduate students with ideas and research concepts that are foreign to their research projects, and expect to be challenged by their concepts and insights;
- provide positive feedback and rewards for significant achievements.

Research Associates and Post Doctoral Fellows
There is a growing interest in marine and meat processing by-products as sources of peptides and proteins. Dr. Ndagijimana is focused on extraction of proteins and characterization of their functionality as well as characterization of bioactive peptides.
In addition, Dr. Ndagijimana is researching on how to modify proteins and peptides (by glycation or glycosylation) in order to improve their functionality and bioactivities (eg. antimicrobial activity). Proteins and peptides as well as glycoproteins and glycopeptides are characterized by a repertoire of different techniques including FPLC, UPLC, LC-MS/MS, MALDI-TOF-MS or Orbitrap-LC-MS/MS.
Dr. Khiari is currently involved in process piloting and scaling-up technologies for recovering value added food ingredients from poultry by-products. The scale-up of technologies, developed in Dr. Betti’s laboratory, includes:
- Scaling-up poultry protein isolate extraction process,
- Scaling-up glycosaminoglycan production from poultry bone biomass.
Dr. Khiari is also involved in the research project about functional modification of proteins by the use of high pressure processing technology.
Dr. Satyanarayana is currently working on Functionalized peptides for skin care produced from bovine and poultry collagen biomass.
Bioavailbility of proteins and peptides is a detrimental factor as it measures the physiological activity of molecule. The bioavailability of proteins and peptides is poor due to they susceptibility to degradation by the gastrointeintestinal enzymes and proteases. In this project we aim to increase the bioavailability of collagen peptides by functionalization with amino sugars to increase collagen bioactivity in vitro and in vivo. Two model cell lines Caco-2 cells and fibroblast which represent intestinal and skin type of cells, will be used to measure the bioactivity in vitro and in vivo.
