101 questions with a bioinformatician #34: Katie Pollard

This post is part of a series that interviews some notable bioinformaticians to get their views on various aspects of bioinformatics research. Hopefully these answers will prove useful to others in the field, especially to those who are just starting their bioinformatics careers.


Katie Pollard is a Senior Investigator at Gladstone Institutes and a Professor in the Department of Epidemiology and Biostatistics at UC San Francisco. She is also a Faculty supervisor of a bioinformatics core that provides collaborative support for high-throughput biology across the UCSF campus.

Katie's work involves the development of statistical and computational methods for the analysis of large genomic datasets, with a particular interest in genome evolution and identifying sequences that differ significantly between or within species. Her work on the chimpanzee genome has led to lots of coverage by mainstream media, and if you want to know more about this topic, you should definitely watch the What makes us human? talk that she gave at the California Academy of Sciences (video is online here).

You can find out more about Katie by visiting her lab's website. And now, on to the 101 questions...



001. What's something that you enjoy about current bioinformatics research?

Growth in new sources of data, such as from citizen science and electronic medical records, as well as emerging technologies, like single cell imaging and genomics platforms.



010. What's something that you don't enjoy about current bioinformatics research?

Computing in the cloud is promising, but it is still to expensive to store massive data for ongoing active compute and too slow to move data into the cloud and out again for each analysis.



011. If you could go back in time and visit yourself as a 18 year old, what single piece of advice would you give yourself to help your future bioinformatics career?

Keep taking math classes.



100. What's your all-time favorite piece of bioinformatics software, and why?

The UC Santa Cruz Genome Browser: you cannot underestimate the importance of looking at raw data, and the browser provides a way visualize a lot of data for every position of the genome. It is easy to check if your assumptions are right or not.



101. IUPAC describes a set of 18 single-character nucleotide codes that can represent a DNA base: which one best reflects your personality, and why?

S for strong.

An automated attempt to identify duplicated software names

From time to time I've been pointing out instances of duplicated software names in bioinformatics. I assume that many people reuse the name of an existing tool simply because they haven't first checked — or checked thoroughly — to see if someone else has already published a piece of software with the same name.

I am not alone in my concern over this issue and Neil Saunders (@neilfws on twitter) has gone one step further and written some code to try to track down instances of duplicated names. He recently wrote a post on his What You're Doing Is Rather Desperate blog to explain more:

In the article, he describes how he used a Ruby script to parse the titles of articles downloaded from PubMed Central and then feeds this info into an R script to identify examples of duplicated software names. The result is a long list of duplicated software names (available on GitHub).

I'm not surprised to learn that generic names like 'FAST' and 'PAIR' appear on this list. However, I was surprised to see that in the same year (2011), two independent publications both decided to name their software 'COMBREX':

BUSCO — the tool that will hopefully replace CEGMA — now has a plant-specific dataset

With the demise of CEGMA I have previously pointed people towards BUSCO. This tool replicates most of what CEGMA did but seems to be much faster and requires fewer dependencies. Most importantly, it is also based on a much more updated set of orthologous genes (OrthoDB) compared to the aging KOGs database that CEGMA used.

The full publication of BUSCO appeared today in the journal Bioinformatics. I still haven't tried using the tool, but one critique that I have seen by others is that there are no plant-specific datasets of conserved genes to use with BUSCO. This appears to be something that the developers are aware of, because the BUSCO website now indicates that a plant dataset is available (though you have to request it).
