Teaching I have taught several courses in several Faculties and at the Ph.D. level in Physics. The students have always rated the quality of my teaching as excellent. For example, in recent years, for the compulsory course of Modern Physics (Introduction to Special Relativity and Quantum Mechanics for second year students (around 100 students) in Physics I obtained the following marks (official data of Padua University): Global Satisfaction Clarity in teaching Ability to stimulate interest in the subject 8.5/10 8.8/10 9.1/10 During my teaching activity I have always tried to promote interdisciplinary courses with particular attention to the applications of physics to biology and medicine. Following my proposal, the Degree course in Molecular Biology at Padua introduced a second course in Physics in addition to the basic level one. This is the only such case in Italy. I taught this course (Complements of physics and Mathematics) for 5 years. In 2003 I was able to promote a programme in Biophysics within the second level degree in Physics. Since 2010 I have taught “Biological Physics” within this programme. Last year the number of students attending the course was 25, making it the most popular among the noncompulsory courses of the Physics degree. 2 Over the years I have supervised 40 thesis (vecchio ordinamento, laurea triennale and magistrale and dottorato). Among my student I mention Cristian Micheletti who is now Full Professor in SISSA and Antonio Trovato who is now Associate Professor in Padova.

I have been member of a National Commission to assign a temporary research position (RTDa) in Genova (2012) N.B.: Of all my management activities, the most difficult and time-consuming was the one regarding the opening of the new Corso di Laurea in Ottica ed Optometria. This degree was the second to start in Italy. I had to tackle several problems from the beginning, contending with the initial opposition of the Faculty of Medicine and the lobby of Ophthalmologists. I had to find 8 grants (and I was able to get the support of Camera di Commercio di Padova, Ascom di Padova, Federottica), to create a completely new syllabus with new kind of student laboratories (optometry, contact lens) and advertise to inform students all over the country of this new academic possibility. The programme degree started in 2004/2005 and when I left the job everything was settled very well: we had 70 applicants for 40 places on the course. Nowadays in Italy there are 6 Corsi di Laurea in Ottica ed Optometria. Since I am chairman of the Scientific Commission of Physical Science, the amount pro capite obtained by our Department from a constant University budget increased from 6239 Euro (2012) to 7750 Euro (+25%). Grants I won European Fellowship of the “Science Program” (EU SCIENCE fellowship) to be used in Oxford with a supporting grant of 30000 British Pounds . I have been local coordinator of a grant (ex 40%) (principal investigator: Prof. M. Ferrario Modena) funded in 1996.

The software aims to predict which portion of a protein sequence is more prone to form a fibrillar aggregate. The software is based on the scientific publications: A. Trovato, F. Chiti, A. Maritan and F. Seno, Plos Computational Biology 12, 1608-1618 (2006) A. Trovato, F. Seno and S.C.E. Tosatto, Protein Engineering Design and Selection 20, 521-523 (2007) Research activity In the early years of my career, I worked on topics related to critical phenomena and phase transitions. Starting in 1996, I oriented my research towards the application of statistical mechanics to biological problems with particular attention to medical and pharmaceutical applications. The main results I obtained are: 10 Solution of the theta point problem: We were able to determine numerically the bulk[a] and surface[b,c] exponents for linear polymers at the theta point, in 2 dimensions. These results stimulated a strong debate since they were in contradiction with the existing theory proposed by Duplantier and Saleur [Phys. Rev. Lett. 59, 3617 (1987)]. Later, we were able to solve the problem exactly[d] by using a mapping on a percolative problem in the presence of a boundary. These results have been completely accepted by the scientific community as the complete solution of the theta point problem and quoted in many reviews, e,g. K. De’Bell and T. Lookman [Surface phase transitions in polymer systems in Reviews of Modern Physics, 65 87, (1993)], and E. Eisenrigler [Polymers near a surface: conformation properties and relation to critical phenomena, Singapore, World Scientific, (1993)] and in the books: C. Vanderzande [Lattice Models of Polymers, Cambridge University Press, 1998] and M. Henkel [Conformal invariance and critical phenomena, Berlin, Springer (1999)]. [a] F. Seno, A.L. Stella, J. Physique, Vol.49, pp.739-748 (1988) [b] F. Seno, A.L.Stella, C. Vanderzande, Phys. Rev. Lett., Vol.61, pp.1520 (1988) [c] F. Seno, A.L. Stella Europhys. Lett., Vol. 7, pp.605-610 (1988) [d] C.Vanderzande, A.L. Stella, F. Seno, Phys. Rev. Lett Vol. 67, pp.2757-2760 (1991), Protein design: We introduced[a] a general method for protein design based on an analysis in sequence space of the Boltzmann weight for a given target structure. We introduced different approaches to implement this method. In particular, by using a free energy expansion based on the amino acid concentrations[b] we were able to successfully design on a cubic lattice (Harvard- San Francisco test) 10 structures of length 48 within the hydrophobic polar (HP) classification of the amino acids. With the same classification of the amino acids, we generalized[c] the method to design real proteins with a success rate of 75% . These results were highlighted in the divulgation journals “Scientific Computing World” (April 1998, p. 8) and “Le Scienze” (July 1998, p. 15). [a] F.Seno, M. Vendruscolo, A. Maritan, J.R.

Banavar, Proteins: Structure, Function, and Genetics, 32, pp 80-87 (1998) Topological properties of proteins: In the work [a] we demonstrated the important role played by the geometrical and topological properties of the native state in determining the folding properties of a protein. Strikingly, by studying the conformational entropy of a backbone it was possible to identify the peptide regions that come in contact at early stages of folding with no detailed information on the sequences that are housed in the target fold. These results regarding the folding nucleus are fully consistent with experimental findings. Even today, this paper is still regularly quoted in the literature (more than 110 citations). Later on , we introduced a novel and fully automated criteria for an optimal partitioning of a complete data bank of protein fragments . We proved that with only a few dozen of such fragments (length 6 aminoacids), virtually any protein can be reproduced within typical experimental uncertainties. [a]C. Micheletti, J.R. Banavar, A. Maritan and F. Seno PRL 82, pp. 3372-3375 (1999) [b] C. Micheletti, F. Seno, A. Maritan, Proteins 40, 662 (2000) 11 General framework to understand the structural properties of proteins: In a set of papers[a,b,c] we proposed that native-state folds of proteins can emerge on the basis of considerations of geometry and symmetry. We showed that the inherent anisotropy of a chain molecule, the geometrical and energetic constraints placed by the hydrogen bonds and sterics, and hydrophobicity are sufficient to yield a free-energy landscape with broad minima even for a homopolymer. These minima correspond to marginally compact structures comprising the menu of folds that proteins choose from to house their native states. This result justifies the well-known fact (Denton and Marshall Nature 410, 417, 2001) that the number of protein folds is limited and not subject to evolution. The fact that possible folds can be determined only by using a homopolymer was confirmed in a more recent paper [d]. Using a sophisticated numerical approach, we performed an exhaustive exploration of the conformational space of a 60 amino acid polypeptide chain described with an accurate all-atom interaction potential. We found an ensemble of almost 7000 independent structures in which it is possible to find all the folds which are known for similar lengths. However, the ensemble of known folds forms a relatively small corner of this ensemble. Many more proteins are possible. Our analysis suggests that existing proteins were evolutionarily selected under the guidance of a simple principle: reducing the entanglement in the bundle formed by the protein in its folded state. This makes bundles with shorter loops preferable. The set of structures that we make available will potentially open a range of practical applications in biomedical sciences. [a] T.X. Hoang, A.

In the course of my research work I have published several papers on this topic which were well accepted by the scientific community[a,b,c,d]. Very recently[e, f] we proposed a novel statistical potential constructed by Bayesian analysis measuring a few structural observables on a set of 500 experimental protein structures. Even though employing many fewer parameters than current state-of-the-art methods, our potential is capable of discriminating with unprecedented reliability the native state in large sets of misfolded models of the same protein.

Comm. 184, 2860 (2013) Amyloid fibrils: 12 An increasing number of terrible human pathologies (such as Alzheimer’s and Parkinson’s diseases) are associated with the conversion of peptides and proteins from their soluble functional forms into well-defined fibrillar aggregates called amyloids. In ref. [a] and [b,c] we developed an algorithm to predict the portions of a sequence, for an initially unstructured polypeptide chain, that stabilizes the cross-beta core of the amyloid fibrils. Our predictions are extremely accurate when compared with experimental findings and they can be used to design mutations that could mitigate the aggregation process and therefore used for therapeutic applications. Our method is available on a web site (http://protein.bio.unipd.it/pasta/) (16000 download). Moreover, the related software we produced (Palmo) was sold, in 2011, by Padua University to the pharmaceutical company Boehringer Ingelheim. [a] A. Trovato, F. Chiti, A. Maritan and F.

The large quantity of experimental results was demanding for theoretical modelling. In this field we have proposed and solved, both numerically and analytically[a,b,c,d,e] several models giving a well-recognized contribution to the field. In particular, we have suggested [a,b] the existence of cold denaturation of a double stranded biopolymer (e.g. DNA) under mechanical stress. Such a transition has not yet been seen experimentally, but the accuracy of our calculation was confirmed in an extended range of temperatures. (C. Danilowitz, Y. Kafri, R.S. Conroy et al. [Phys.

We proposed [a] a measure to quantify the nature of data collapse, e.g for establishing scaling and extracting the associated exponents in problems showing self-similar or self-affine characteristics, for example, in equilibrium or non-equilibrium phase transitions . Via a minimization of this measure, the exponents and their error bars can be obtained. The methods works remarkably well and it has been used in a variety of problems such as the dynamics of ecological communities and the study of biological networks. [a] S.M. Bhattacharjee and F. Seno , J. Phys. A, Vol. 33, pp.6375-6380 (2001) Efimov effect for polymer physics 13 We proposed [a] and directly verified on an exactly solvable model[b] that the cold atom quantum Efimov effect, namely the possibility of a three body bound state where none of the pairs is bound, can be observed in thermal denaturation of three strand polymeric systems. This observation might have important and unexpected implications in a biological context where many processes involved three polymers (e.g. three helix DNA) [a] J. Maji, S.M. Bhattacharjje, F.

E89, 012121 (2014) Quorum sensing Quorum sensing can be described as the regulation of gene expression in response to changes in the bacterial population density. In this emerging field of microbiology we have introduced specific modeling which takes into account the presence of different boundary conditions and our calculations motivated dedicated experiments that we performed in collaboration with experimentalists of our university (Squartini, Brun). Our results have been quoted in the book by Stephen Hagen “The physical basis of Bacterial Quorum Communication”that is the first monography ever written on this subject. [a] S.
