Every year I ask some of the attendees of the ScienceOnline conferences to tell me (and my readers) more about themselves, their careers, current projects and their views on the use of the Web in science, science education or science communication. So now we continue with the participants of ScienceOnline2012. See all the interviews in this series here.
Today my guest is Kaitlin Vandemark (blog, Twitter)
Welcome to A Blog Around The Clock. Would you, please, tell my readers a little bit more about yourself? Where are you coming from (both geographically and philosophically)? What is your background? Any scientific education?
Hello, my name is Kaitlin Vandemark. I am currently a student at Cleveland State University studying physics and communications. I was originally studying to get a bachelor?s degree in physics, until I started to become more interested in communications and finding a way of expressing my love of science to others. I will graduate in December of 2013 with my bachelors in both Physics and Communications. I am hoping then to find a career that allows me to pursue my passion in both science and communication.
Tell us a little more about your career trajectory so far: interesting projects past and present?
I am still a bit new to the field of online communications. Like anyone from my generation, I have a Facebook and Twitter, but only recently have I started to expand on my online science communication. For the past 2 and ? years I have been doing optics research at my university. This research has allowed me to attend many conferences, where I can present my research and passion for science to others.
After attending Science Online 2012, I have started a website with AmoebaMike. The site is called the Sardonic Scientist, and its main focus is to parody science news. We have been trying to jumpstart the website with new articles, and I am very excited to see the website grow.
What is taking up the most of your time and passion these days? What are your goals?
School takes up most of my time these days. Between classes, clubs, student government, and research; I am kept pretty busy. I write articles for the website whenever I have free time. As I near graduation my next goals consist of finding a career path. I have been researching companies and graduate schools to decide my next steps. I am currently torn between entering industry after my bachelors or continuing my education with graduate school in physics or communications.
What aspect of science communication and/or particular use of the Web in science interests you the most?
I think Science Communication (especially through the web) is important because of the misuse of science today. Many people rely on the internet to get information, and form ideas about issues that face society today. Unfortunately, many people use science as a tool to gain support for their ideas; whether or not the science they claim is true. I can?t tell you how many times I have heard someone quote a scientific study of some sort to prove a point that doesn?t even relate to the original studie?s goal. This misuse of science motivates me to communicate science to the world. I do this in the hopes that they will do their research before believing in false claims.
How does (if it does) blogging figure in your work? How about social networks, e.g., Twitter, Google Plus and Facebook? Do you find all this online activity to be a net positive (or even a necessity) in what you do?
Currently I do not blog much but social networks have a huge effect on my activities. I use Twitter and Facebook to not only connect with people, but to promote my activities. I am currently involved in the Society of Physics Students at my University as well as Student Government. I use Twitter and Facebook to promote events to students. I also use Twitter and Facebook to promote the Sardonic Scientist, by posting new articles on each site.
What was the best aspect of ScienceOnline2012 for you? Any suggestions for next year? Is there anything that happened at this Conference ? a session, something someone said or did or wrote ? that will change the way you think about science communication, or something that you will take with you to your job, blog-reading and blog-writing?
This is a very difficult question for me. ScienceOnline2012 was such a great experience that it was hard to pick one aspect. This was the first conference I have been to of this nature. I have been to dozens of scientific conferences, but they seem to be filled with nothing but talks and seminars. This was the first conference to encourage the attendants to speak to each other and share ideas openly in forum. I would say my favorite aspect of the conference was the fact it was an ?unconference?, this opened up my eyes to a new way of communicating in science.
Another great aspect was meeting new and wonderful people. Without this conference I would not have meet AmoebaMike and started our website.
Every session I went to offered new ideas and helpful hints for succeeding in science communication. My two favorite sessions were the ?2 Minute Elevator Pitch Session? and ?Science Communication the Mel Brooks Way?. Each of these sessions provided me with a different tool to succeed at my career. The Elevator pitch session helped me to prepare for my career, whether it is in the university setting or industry. The Mel Brooks session confirmed my love of humor to spread knowledge. I have always firmly believed that humor is a useful tool to teach, but it was amazing to see so many people in one room who believed the same.
For this upcoming ScienceOnline I would definitely stick with the ?unconference? idea. I would be interested in a session for new bloggers who are interested on tips to get started.

World's fastest camera, created by UCLA engineers, used to detect rogue cancer cellsPublic release date: 5-Jul-2012 [ | E-mail | Share ]

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.
Circulating cancer tumor cells are a perfect example. Typically, there are only a handful of them among a billion healthy cells, yet they are precursors to metastasis, the spread of cancer that causes about 90 percent of cancer mortalities. Such "rogue" cells are not limited to cancer they also include stem cells used for regenerative medicine and other cell types.
Unfortunately, detecting such cells is difficult. Achieving good statistical accuracy requires an automated, high-throughput instrument that can examine millions of cells in a reasonably short time. Microscopes equipped with digital cameras are currently the gold standard for analyzing cells, but they are too slow to be useful for this application.
Now, a new optical microscope developed by UCLA engineers could make the tough task a whole lot easier.
"To catch these elusive cells, the camera must be able to capture and digitally process millions of images continuously at a very high frame rate," said Bahram Jalali, who holds the Northrop Grumman Endowed Opto-Electronic Chair in Electrical Engineering at the UCLA Henry Samueli School of Engineering and Applied Science. "Conventional CCD and CMOS cameras are not fast and sensitive enough. It takes time to read the data from the array of pixels, and they become less sensitive to light at high speed."
The current flow-cytometry method has high throughput, but since it relies on single-point light scattering, as opposed to taking a picture, it is not sensitive enough to detect very rare cell types, such as those present in early-stage or pre-metastasis cancer patients.
To overcome these limitations, an interdisciplinary team of researchers led by Jalali and Dino Di Carlo, a UCLA associate professor of bioengineering, with expertise in optics and high-speed electronics, microfluidics, and biotechnology, has developed a high-throughput flow-through optical microscope with the ability to detect rare cells with sensitivity of one part per million in real time.
This technology builds on the photonic time-stretch camera technology created by Jalali's team in 2009 to produce the world's fastest continuous-running camera.
In the latest issue of the journal Proceedings of the National Academy of Sciences, Jalali, Di Carlo and their colleagues describe how they integrated this camera with advanced microfluidics and real-time image processing in order to classify cells in blood samples. The new blood-screening technology boasts a throughput of 100,000 cells per second, approximately 100 times higher than conventional imaging-based blood analyzers.
"This achievement required the integration of several cutting-edge technologies through collaborations between the departments of bioengineering and electrical engineering and the California NanoSystems Institute and adds to the significant technology infrastructure being developed at UCLA for cell-based diagnostics," Di Carlo said.
Both Jalali and Di Carlo are members of the California NanoSystems Institute at UCLA.
Their research demonstrates real-time identification of rare breast cancer cells in blood with a record low false-positive rate of one cell in a million. Preliminary results indicate that this new technology has the potential to quickly enable the detection of rare circulating tumor cells from a large volume of blood, opening the way for statistically accurate early detection of cancer and for monitoring the efficiency of drug and radiation therapy.
"This technology can significantly reduce errors and costs in medical diagnosis," said lead author Keisuke Goda, a UCLA program manager in electrical engineering and bioengineering.
The results were obtained by mixing cancer cells grown in a laboratory with blood in various proportions to emulate real-life patient blood.
"To further validate the clinical utility of the technology, we are currently performing clinical tests in collaboration with clinicians," said Goda, also a member of the California NanoSystems Institute. "The technology is also potentially useful for urine analysis, water quality monitoring and related applications."

World's fastest camera, created by UCLA engineers, used to detect rogue cancer cellsPublic release date: 5-Jul-2012 [ | E-mail | Share ]

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.
Circulating cancer tumor cells are a perfect example. Typically, there are only a handful of them among a billion healthy cells, yet they are precursors to metastasis, the spread of cancer that causes about 90 percent of cancer mortalities. Such "rogue" cells are not limited to cancer they also include stem cells used for regenerative medicine and other cell types.
Unfortunately, detecting such cells is difficult. Achieving good statistical accuracy requires an automated, high-throughput instrument that can examine millions of cells in a reasonably short time. Microscopes equipped with digital cameras are currently the gold standard for analyzing cells, but they are too slow to be useful for this application.
Now, a new optical microscope developed by UCLA engineers could make the tough task a whole lot easier.
"To catch these elusive cells, the camera must be able to capture and digitally process millions of images continuously at a very high frame rate," said Bahram Jalali, who holds the Northrop Grumman Endowed Opto-Electronic Chair in Electrical Engineering at the UCLA Henry Samueli School of Engineering and Applied Science. "Conventional CCD and CMOS cameras are not fast and sensitive enough. It takes time to read the data from the array of pixels, and they become less sensitive to light at high speed."
The current flow-cytometry method has high throughput, but since it relies on single-point light scattering, as opposed to taking a picture, it is not sensitive enough to detect very rare cell types, such as those present in early-stage or pre-metastasis cancer patients.
To overcome these limitations, an interdisciplinary team of researchers led by Jalali and Dino Di Carlo, a UCLA associate professor of bioengineering, with expertise in optics and high-speed electronics, microfluidics, and biotechnology, has developed a high-throughput flow-through optical microscope with the ability to detect rare cells with sensitivity of one part per million in real time.
This technology builds on the photonic time-stretch camera technology created by Jalali's team in 2009 to produce the world's fastest continuous-running camera.
In the latest issue of the journal Proceedings of the National Academy of Sciences, Jalali, Di Carlo and their colleagues describe how they integrated this camera with advanced microfluidics and real-time image processing in order to classify cells in blood samples. The new blood-screening technology boasts a throughput of 100,000 cells per second, approximately 100 times higher than conventional imaging-based blood analyzers.
"This achievement required the integration of several cutting-edge technologies through collaborations between the departments of bioengineering and electrical engineering and the California NanoSystems Institute and adds to the significant technology infrastructure being developed at UCLA for cell-based diagnostics," Di Carlo said.
Both Jalali and Di Carlo are members of the California NanoSystems Institute at UCLA.
Their research demonstrates real-time identification of rare breast cancer cells in blood with a record low false-positive rate of one cell in a million. Preliminary results indicate that this new technology has the potential to quickly enable the detection of rare circulating tumor cells from a large volume of blood, opening the way for statistically accurate early detection of cancer and for monitoring the efficiency of drug and radiation therapy.
"This technology can significantly reduce errors and costs in medical diagnosis," said lead author Keisuke Goda, a UCLA program manager in electrical engineering and bioengineering.
The results were obtained by mixing cancer cells grown in a laboratory with blood in various proportions to emulate real-life patient blood.
"To further validate the clinical utility of the technology, we are currently performing clinical tests in collaboration with clinicians," said Goda, also a member of the California NanoSystems Institute. "The technology is also potentially useful for urine analysis, water quality monitoring and related applications."

Hello, my name is Kaitlin Vandemark. I am currently a student at Cleveland State University studying physics and communications. I was originally studying to get a bachelor?s degree in physics, until I started to become more interested in communications and finding a way of expressing my love of science to others. I will graduate in December of 2013 with my bachelors in both Physics and Communications. I am hoping then to find a career that allows me to pursue my passion in both science and communication.![[ Back to EurekAlert! ]](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_tiorT2BPBu3BBY_do5vi8sZz6k-TlEwf4SAWgQKlVGUa4bNqd6opLQtO7b_YvVr8JqNrmFegLdXssGJqX8lPxnUoLvp5vlJ3RtRcn2FeY=s0-d){kind=small}
