Let's Meet Stephanie Smith  - YSI's Newest Product Manager

As the new Product Line Manager for our Environmental Monitoring Instrumentation systems that focus Stephanie Smithheavily on long-term water quality monitoring solutions, I want to introduce myself to customers and colleagues at Xylem. Nobody wants to hear a scientist drone on about their resume (though I’m happy to oblige requests), so in sum my background spans academia to industry, pure research to serving most recently as the co-founder and CSO/COO of a small business.   

Many of my customers at that business started using EXO1 and EXO2 sondes to monitor harmful algal blooms in 2015.  The EXO line was new to me and served as a reminder that YSI is always on the leading edge of technology, and that 20 years after I first heard of them in grad school, YSI still produces the highest-quality and most reliable environmental monitoring products. It is thus with an appreciation for that history, and excitement for the future, that I take on this role.

So what does that future look like? Obviously I’m still figuring that out, but here’s what I see after my first month on the job. First, the EXO line will continue to be a leading platform technology. Our team regularly reviews ideas for new types of sensors (look for future blogs on emerging ideas), and we are planning some exciting announcements on EXO sensors in 2017. 

Second, in both new product development and current product upgrades, we will continue to be guided by our customers’ needs. A great demonstration of that is the launch of the new EXO handheld this summer. The lighter, ergonomic design of the EXO handheld is the result of 4+ years of customer feedback, as are the new built-in rechargeable battery, integrated USB, user-configured calibration reminders, and number of other features. YSI has always been committed to helping customers collect the highest-quality data, and in this case we heard from customers how they needed to do that and we responded accordingly.

Lastly, I hope that we will introduce the EXO platform into new markets, in terms of both scope and geography, because the possibilities with the EXO platform are truly endless. In fact, I’m curious—what possibilities do you see for the EXO platform in the future? Now that you know a little about me, I’d like to hear from you!

Dear Dr. Smith, I am a supervisory chemist. Recently I was tasked to develop phycocianin and phycoerythrin method (fluorometric) for my lab. Do you know if there is an approved method? I could not find it. Thanks in advance for your time!


As I understand it, chlorophyll a and pheophytin a have a fair amount of overlap in the bandwidth in which they fluoresce. (French, C.S. and others. 1956. Fluorecence-Spectrum Curves of Chlorophylls, Pheophytins, Phycoerythrins, Phycocyanins and Hypericin. Plant Physiology Sep; 31(5): 369-374.) So when comparing monitored chlorophyll a values from the EXO2 Total Chlorophyll sensor to grab samples processed using EPA methodology should I be including the combined value of chlorophyll a and pheophytin a as reported from the lab? I would be grateful for any guidance. Sincere regards, David Fazio U.S. Geological Survey Illinois Water Science Center
