“Don’t give a talk, take a class.” This was the driving force, as I feel, behind the SAMSI Workshop on Statistical Methods for Bioinformatics we had at the IISc campus, India during Dec 12-14, 2013. It included people from diverse backgrounds encompassing biologists, statisticians, mathematicians, computer scientists, biostatisticians, biophysicians, biochemists, anthropologists, and lot more.

The Department of Mathematics at IISc was a perfect inspiring venue for this workshop, particularly for research discussions. It has chalks and boards kept everywhere, at every corner of the department! Even I saw a catering person to write random equations (although trivial) on a board avoiding others’ notice. Environment really motivates!

The very first talk of the workshop, by Varghese George of Georgia Regents University, made us feel like entering into the revitalized world of the epigenetics. The recent progresses and futuristic goals were very nicely introduced. Both Indranil Mukhopadhyay of ISI Kolkata and S. R. Deshmukh of University of Pune had comprehensive introductory talks afterwards about the basics of statistical tests, molecular biology, etc. and about expression profiling, respectively. Many of the speakers were also benefited from their efforts of making a strong foundation of the preliminary concepts. It was not required for them to start from the scratch.

The first day was so windy that I felt possibly the air is also keen to enter into the lecture hall, a perfect learning platform! What I liked most is not only the respective speakers were responding to the questions, rather everybody took the pain to discuss and settle the best answer for the tricky ones. The sessions were not too much attendee-heavy, so everybody had a fair chance of asking questions. Again, the ratio close to 2:3 between the invited speakers and the participants set up a real platform of face-to-face learning.

Naomi Altman of Pennsylvania State University gave an attractive talk on the recent obesity of the high throughput data. The reproducibility of research became a major issue of discussion lead by the talk of Prof. Altman. It is really a burning issue worldwide. There was a common agreement between all the invited speakers, who strongly encouraged keeping the relevant source codes also available alongside the publications.

How statistical analysis can help in some particular areas of plant genetics, especially in the gene duplication problems, was thoroughly described by the SAMSI Deputy Director Snehlata Huzurbazar. It was also a real pleasure to have Ashis Sen Gupta of ISI Kolkata on stage to talk about his work on understanding the circadian rhythms. It is a real challenge to build statistical models given the surprising fact that “the rhythm of the life is circular, although the life is itself a linear game.”

The next day we also had a great experience! Everybody was cracking jokes with the “Friday the 13th” issue that eventually marked out the second day of the workshop. But it was really an enjoyable day – not only for the banquet but also for the diversity and depth of the talks. It started with the talk by Nagasuma R. Chandra from the host institute who gave a realistic overview of how to proceed step-by-step towards the modelling of disease prediction. She has a strong belief that making such systems automated will indeed speed up the progresses in this direction.

Olga Vitek from Purdue University gave us an all-inclusive glance toward the immense scope lying in some promising areas of proteomics. Again, N. Srinivasan of IISc detailed on a fantastic account of his research on finding missing links between protein families using computational models.

T. S. Vasulu of ISI Kolkata and Paul Joyce (I love the way he explains complex things with funny examples) of University of Idaho gave nice introductions to statistical methods that can be applied to phylogenetic analysis and for the study of adaptive evolution, respectively. Switching between the laser pointer and the hard pointing stick was a real fun for Prof. Joyce.


Every talk was made somewhat flexible based on the demand of the attendees. I remember a talk to have been stretched by half an hour or so to satisfactorily answer every question raised by the listeners. Still the overall time frame for the entire day was well maintained. We also had a nice photo session on the terrace of the hosting department in a mood of get together.

The long walks (voluntarily avoiding cars) through the woods of the campus of IISc with many of the speakers, while returning after the workshop days, gave me pleasant chance of gaining additional experience through informal discussions. Research is no more an independent effort, rather a collaborative competition.

The final day of the workshop started with a nice talk by Susan Holmes of Stanford University, who highlighted diverse facets of the Human Microbiome Project. Her idea of more on leaps less on slides was great, using the chalks and boards every time. The concluding talk by Sanghamitra Bandyopadyay of ISI Kolkata, a very basic one bridging between statistics, computer science and biology, detailed on various robust computational models that can tackle multi-objective problems, often occurring in expression analysis and related areas.

The contributory talks by seven of us, mostly covering ongoing studies, were strongly benefitted from the expert speakers being also a part of the audience. I enjoyed my contributed talk and received a couple of valuable suggestions. The take home message was “do whatever you wish to do, but with a clear conception and full confidence.” We were unfortunate this time to miss the talk of K. Thangaraj of CCMB, on the very last day because of his absence due to some urgent involvements.

I hope that the slides of the talks will soon be available online. The logistics managed by Shruti and Sai were fabulous. The foods were so diverse that I experienced the taste of the entire India. The organizers took a lot of pain to arrange a great banquet dinner on the second day. The round table discussions in the banquet session were really effective.

I feel like SAMSI workshop proved to be a real SAMSI (such a mega statistical incident). Hats off SAMSI!
