Left: Gilles Ponchel (standing), then a PhD student with Dominique Duchene, now professor of pharmacy at the University of Paris-Sud. Gilles, Dominique, Nicholas and Dennis (see previous picture) developed the tensiometric technique of mucoadhesive material analysis and published five papers on various aspects of the analysis. Sitting with a red sweater is Serge Segot-Chicq, who did his DEA under Nicholas’ supervision and spent 8 months at Purdue working on novel swellable systems based on ethylene-vinyl alcohol. Serge is now a senior manager of pharmaceutical research with Sanofi-Aventis in Anthony, France. Right: Olivier Saslawski (sitting) who did his doctorate under the supervision of Nicholas and Prof. Patrick Couvreur. Olivier was the first to show that temperature sensitive carriers could be used for therapeutic protein delivery. His 1988 APGI paper on insulin delivery is one of the earliest references in the field. Standing at right are Nicholas Peppas (seen partially behind Dominique Duchene), Dominique Duchene, Francis Puisieux and Patrick Couvreur. (December 1986)

Prof Peppas giving the plenary lecture of the Fourth International Conference on Pharmaceutical Technology organized by APGI in Paris, France on June 4, 1986.

Dinner in honor of the invited speakers of the Fourth International Conference on Pharmaceutical Technology organized by APGI. This dinner was held on June 6, 1986 at the Monmarte restaurant L’Assommoir, a favorite of Parisians and especially our noble hostess Professor Dominique Duchene, President of APGI for almost two decades. The restaurant was named after the seventh novel in Émile Zola's twenty-volume series Les Rougon-Macquart. Usually considered one of Zola's masterpieces, the novel - a harsh and uncompromising study of alcoholism and poverty in the working-class districts of Paris - was a huge commercial success and established Zola's fame and reputation throughout France and the world. In this picture, from right: Prof Stelios Malamataris of the University of Thessaloniki, Prof Peppas, Professor Yvette Pourcelot of the University of Dijon, ?, and Professor Dominique Duchene of the University of Paris-Sud.

Nicholas Peppas and Bob Haluska receive awards at the 12th International Symposium on Controlled Release of Bioactive Materials, Geneva, Switzerland. This meeting is otherwise known as the Controlled Release Society meeting. The 1985 meeting was the first one organized outside of the USA and it was a great success. The organizers were Professors Peppas and Robert Gurny (University of Geneva) (July 1985)

On December 19, 1984, the Indianapolis Star announced in its first page the first mucoadhesive systems developed in Peppas’ laboratories, through early collaboration of Pierre Buri of the University of Geneva and our group. The very early Purdue researchers in the mucoadhesion field were Jennifer Sahlin, L. Achar, Natalie Wisniewski, Esmaiel Jabbari and Jennifer Bauerle.

Three Genevois PhD students who did part of their PhD research under the supervision of Prof Peppas. All three spent some time in our laboratories at Purdue. From left: Bruno Gander (now Professor of Pharmacy at ETH Zurich) who worked on poly(vinyl alcohol) micromatrices for drug delivery (co-advisors: Eric Doelker and Robert Gurny), Christian Robert (now with the cantonal government in Geneva) who worked on swellable microparticles for release of poorly soluble drugs (co-advisor: Pierre Buri), and Christian Bindschaedler (now at Merck-Serono in Geneva) who worked on advanced modeling of colloidal structures and their drug partitioning (co-advisors:Eric Doelker and Robert Gurny)

Upon completion of Prof Peppas’s first sabbatical at the University of Geneva, Switzerland (August-December 1982), a good bye dinner was given in his honor. In that dinner Professor Peppas and Professor Pierre Buri read the beginning of the Iliad of Homer, Nicholas in modern Greek, Pierre in Erasmian Greek. The great collaboration between the Peppas lab and the Buri/Doelker/Gurny labs started in 1978 and continued until 2006 when the last of 37 papers, a highly cited review on chitosans, was published!

A corner of our first lab in CMET 210 in August 1980. An early Waters GPC can be seen on the left. In those early days Peppas had two labs (210 and 212) in the second floor of the then CMET building (built in 1938). The benches had been brought from … the salvage rooms of Purdue University as there were no Departmental funds for lab building or renovation. But NSF and NIH research funding had already started and the labs were very well equipped. Peppas’s office was in room 210A. One had to pass through the lab 210 to enter his office. There was no emergency exit to the corridors. These were truly different days….

Our first biomedical lab in the Potter building in March 1980. At that time, Dean Hancock had allocated this lab for the biomedical and biomaterials work. Steve Ash, Ron Barile and Nicholas Peppas had their laboratories there, and most of the portable artificial kidney work was done in these labs. Ray Davidson's and Don Miller's PhDs were conducted here.
