Current Group Members:


PI:  Prof. Peter R. Andreana, PhD


Peter received his Hons. BSc in Biochemistry (heavy emphasis on Organic) from Brock University in St. Catharines, Ontario, Canada in 1998 under the tutelage of the late Prof. H. L. Holland.  His Honors thesis is titled: "An Investigation of the Sulfoxidation of N-Protected Amino Acids by Beauvaria bassiana ATCC 7159".  He then received his PhD in 2002 from Wayne State University, Detroit, MI working in the labs of Prof. P. G. Wang. His Dissertation is titled: "Chemoenzymatic Synthesis of Biologically Significant Carbohydrates".  In 2002 he moved to Harvard University in Cambridge, MA to work first as a Post Doctoral Associate and then as an NIH Ruth L. Kirschstein Post Doctoral Fellow for Prof. S. L. Schreiber.  In the Schreiber labs he studied the direction of Diversity-Oriented Synthesis (DOS) which included small molecule synthesis and asymmetric catalysis using multicomponent coupling reactions.  

In 2005, he returned to his PhD granting institute to begin his independent career as an Assistant Professor and in 2012 relocated with his group to The University of Toledo where he is currently Full Professor.  He is both a member of the Department of Chemistry and Biochemistry and School of Green Chemistry and Engineering.  The Andreana Group Research interests can be found on this website but in short the group is interested in carbohydrate-based vaccine development (current directions are cancer and bacterial based), small molecule synthesis (natural and natural product like synthesis) and the development of carbohydrate-based immunotherapeutics.  For all existing efforts, the group operates under an NIH UO1 GM125271-01 and start-up monies from The University of Toledo.  In 2010, the Andreana Group was bestowed an ACS National Award from the Division of Carbohydrate.

Currently Prof. Andreana serves on the United States Advisory Committee for the International Carbohydrate Symposium (USACICS) as treasurer and secretary, the ACS Carbohydrate Division's webmaster and as of January 1, 2020 in the role of ACS Immediate Past Chair for the ACS Carbohydrate Division.

Dr. Samir Ghosh, PhD

Post-Doctoral Associate (2018 - )


Dr. Ghosh came to us from Kolkata, West Bengal, India.  Samir worked on the total synthesis of tumor associated carbohydrate antigens (TACAs) Gb3 and Globo H.  He developed stereoselective chemistries as well as chemistries to facilitate the incorporation of aminooxy functionality that allowed for expedited conjugation to carbonyls.  His hard work and concerted efforts landed him a number of publications which you can see here.  After a short stint back in India at a preeminent pharmaceutical company, Samir is back in the Andreana Group ready to pick up exactly where he left off...dialed in at 100 mph!!!

Dr. Mengchao Shi, PhD

Post-Doctoral Associate (2019 - )


Dr. Shi comes back to us after completing a Postdoctoral Fellowship at The Broad Institute in Boston, MA (see more info below).  Mengchao graduated in 2016 from the AndreanaGroup and since his return has been focused on developing methods for glycosylation reactions.  You can see some of his work here.

Welcome the very newest addition to our group, Mr. Matthew Lohman, who comes to Toledo, Ohio all the way from Edwardsville, Illinois.  Matt is a De Meo alumni and very well trained in the art of carbohydrate assembly, especially in utilizing sialic acid.  Matt received his B.S. degree from Southern Illinois University, Edwardsville in 2018.  He is currently working on understanding carbohydrate binding to proteins.  He is also utilizing his synthetic skill-set to generate sugar donors and acceptors for stitching together biologically significant oligomers.  Matt always brings a positive attitude to the group and we all look forward to seeing him excel over the next few years.

Geraud Valentin

2nd Year Graduate Student (F2019 - )


The Andreana Group is very fortunate to have Mr. Geraud Valentin join us.  He comes to UToledo from Lille in France with an accomplished track record of success.  In 2015, he graduated with a BSc with distinction, he was in the International Chemistry Olympiads in 2016 where he ranked 27th in France and he attended the prestigious ENSCL (Ecole Nationale Superieure De Chimie De Lille).  Geraud has gotten off to a great start here at UToledo with making progress towards carbohydrate conjugation.  In his past time, we have come to learn, first hand, that Geraud loves to cook classic French dishes that are truly delicious!  We expect big things from this young man and look forward to his many scientific accomplishments!  

Mathieu Geremia

2nd Year Graduate Student (F2019 - )


Parlez-vous français?   Peut-être la prochaine fois!!!  Coming to us from the National College of Chemical Engineering in Mulhouse, France, Mr. Mathieu Geremia is a welcomed addition to La Familia!  A multi-lingual talent, including excellent spoken German, Italian and some English (aside from his native tongue), this guy really knows his chemistry as well!   He has aspirations of garnering an MS degree in the Andreana Group and then Mathieu plans to eventually go back to France where he will begin his science career.  Mathieu has also studied in Germany at Albert-Ludwigs Universität in Freiburg-im-Breisgau and in our group he will examine oxidation/conjugation methods for detecting rare, but important nucleotides/nucleosides.  Mathieu is full of energy and we look forward to many great things from him.

Hannah Rowe

1st Year Graduate Student (F2019 - )


Hannah comes to us from Rose-Hulman Institute of Technology – Terre Haute, IN where she obtained her BS in Biochemistry.  Hannah did a summer intern position as a Research Assistant in Marian University, Indianapolis, IN.  She brings a plethora of skills to the team and a great attitude with lots of smiles.  We look forward to watching Hannah bloom as she navigates through the choppy waters of vaccine design and development!
