ABSTRACT:  Both chemical composition and surface structure can influence how a fluid interacts with a surface. Through fluid contact and sliding angle surfaces can be classified as hydrophilic, hydrophobic, superhydrophobic or oleophobic. Our laboratory employs biomimetic and nanoparticle based coatings combined microfabrication methods (e.g. 3-D printing, laser micromachining and plasma exposure) to produce surfaces patterned with different fluid wetting properties.  The slippery and sticky surfaces find significant utility in sample preparation and analysis using droplet-based microfluidics and mass spectrometry approaches.

BIO:  Richard Oleschuk obtained his Hon. B.Sc. (1994) and Ph.D. (1998) from the Department of Chemistry at the University of Manitoba. His doctoral studies with Arthur Chow, involved researching both polymer based extraction methods for metal complexes and membrane sample preparation methods for the mass spectrometry. In 1998, Richard was awarded a Natural Sciences and Engineering Research Council (NSERC) Post Doctoral Fellowship, which he tenured in D. J. Harrison’s laboratory at the University of Alberta. His post-doctoral work involved developing miniaturized analysis devices, incorporating solid phase extraction and electrochromatography into lab-on-a-chips as well as utilizing mass spectrometry as a detector for microfluidic analysis.  Richard joined Queen’s university in 2000 and has remained there since, he was promoted to Associate professor in 2006 and Full professor in 2011. Richard has had two sabbatical leaves in 2007 he was a Swedish Institute Researcher in Thomas Laurell’s laboratory at Lund University, Sweden and in 2015 Richard was a visiting researcher in Dr. Sabeth Verpoorte’s laboratory at Groningen University in the Netherlands. Richard received the Premier’s Research Excellence Award 2002, Fred Beamish Award 2005 and Queen’s University Chancellor’s Award in 2006 and in 2015 Richard was named an Honorary Adjunct Professor at Xi’an Jiaotong University.  Richard has received a number of teaching awards and nominations including the Department of Chemistry Graduating Class Teaching Award, which has been presented with 7 times.

Dr. Oleschuk is the guest of Dr. Dajana Vuckovic
