In April of 2015, I accepted a position with Fluid Imaging Technologies in Scarborough, Maine. It’s been over a year since I began working with this instrumentation company, so I thought I’d share some insight into my non-academic science career.
First, when people ask me what I “do for work”, I tell them that I mostly get to play. That’s because if you’ve been lucky enough to pursue a career where you love what you do for a living, then a “job” is not “work” but rather, your passion. My role is to assist scientists (customers) with using our instrumentation through training and hands-on optimization with their sampling material. Having had a background in FlowCam knowledge from my undergraduate days early on, it’s been a truly full-circle experience coming back to work with this company. It didn’t hurt that I also came to this position after a unique set of skills in the aquatic science field. Never underestimate that training you had in flow cytometry, or that business class you took years back. These days, to succeed in a scientific career, it seems you need a combination of skill sets that one unique degree won’t meet.
So, what do I really do? I travel, answer questions, provide training, run samples, test instrumentation and software, brainstorm ideas, and participate in R&D from order to product. It’s a truly unique position that I’ve never had before. I also find myself in remote places working with people – not just scientists. In the end, we’re a people-driven company that has always focused on providing tools for scientists to do their research. Simply put, we make the tools – it’s up to you to use them! I just show people how to use a particular tool in their toolset.
For those of you who may be interested in following some of the field service work that I conduct, please check out a recent Fluid Imaging blog post about my training trip to Kazakhstan. Here are some great photos from the experience as well!

Brooklyn based artist Daniel Kohn is working with geneticists on conceptual tools to analyze their large data sets. Using intuitive, perceptual learning combined with his artistic approach to data reduction, Kohn is helping these scientists understand new ways to find signal amongst the noise. Starting with a collaboration in 2003 with research groups in Boston that led to a residency with the Broad Institute for Genetic research, at MIT and Harvard, Kohn’s interest in science expanded to include different mediums: painting, drawing, and computer modeling . Since his pioneering collaboration with Broad, Kohn and several other artists have participated in their artist-in-residence program. More information about the program can be found on their webpage.
Shown in the image above, his series “Instance of a Dataset” culminated with a unique mural for the Broad Institute and an ongoing collaboration between artists and scientists. More images from this installation may be found in his gallery online. Kohn’s work speaks to a type of perceptual thinking and visual learning that we all utilize in our daily lives, with the difference that he is putting these tools into experimental approaches to real world datasets. Call it what you will, creative, intuitive, perceptual, or visual learning, these methods are all part of a new approach to thinking about complex data in novel ways.
Here’s another example of sorting out the signal from noise in a simple dataset from my first thesis.
This is a flow cytometric histogram or density plot showing distinctly different populations of marine cyanobacteria from a station sampled off the coast of South America in 2008. The frozen vial of seawater was analyzed by running a small volume through a flow cytometer and the output is literally a cloud of dots like this. Each dot signifies a particle of a particular size with unique fluorescence properties. The goal is to quantify this mess and distinguish between the background noise and populations of interest. This is accomplished easily with out of the box image analysis software and careful knowledge of the properties inherent in the type of data you’re working with – but there’s still an intuitive nature to this analysis. It can be subjective and open ended when you are hand selecting groups of dots and making artificial cut-offs. There are no steadfast rules to this type of data analysis, and you must be the kind of scientist that can work with imperfect data.
I recently finished a 3-year fellowship working on a unique time-series dataset to extract patterns. Most of my work involved the application and understanding of statistical models. There was a lot of time in front of messy data. There were a lot of visual tools and head scratching. There were things like this simple heat-map that took too much time to construct, a lot more data points that you can imagine – but resulted in a visually interesting approach to think about a dataset.
Using this type of approach leaves the data open to interpretation in a sometimes fuzzy manner, but from the vast types of data and rapidly evolving software, there are new and beautiful ways to think about your science. I’ll feature innovative artists and scientists from time to time on this webpage. Feel free to comment or ask further questions about my previous work.

In today’s BBC Nature news:
After a cold spell, British scientists are concerned about the late arrival of rare butterfly species.
Although my current research is focused primarily on marine plankton phenology, dramatic examples of year to year changes in terrestrial biology are interesting to mark. The recorded observations of flowering events, leaf-out, ice-out and annual migratory patterns comprise phenology across many different ecosystems. Shifting phenological timing due to climatic conditions is difficult to track unless long-term records of both climate and species occurrences are marked.
In contrast with previous year’s observations, the timing of this year’s insects was up to a month later. What role do rare species play in this complex ecosystem interplay of phenological timing and response to environmental conditions?
