Coulter \u2014 legendary scientist and inventor of a device to rapidly count cells \u2014 was elected as a fellow of the American Institute for Medical and Biological Engineering (AIMBE), he was unable to attend the meeting to accept the nomination. Rather than mail the award to him, Georgia Tech\u2019s Robert Nerem, who was AIMBE\u2019s president at the time, hopped on a plane from Atlanta and flew to Miami to present Coulter with the award in person.\u003C\/p\u003E\u003Cp\u003EAmong his many titles, Nerem is the founding director of Georgia Tech\u2019s Parker H. Petit Institute for Bioengineering and Bioscience. He has been a bioengineer for more than 35 years. Nerem knew how important Coulter was to the field, but the man he met in Miami gave no hint of scientific or business celebrity.\u003C\/p\u003E\u003Cp\u003E\u201cHe was a fascinating individual, very humble in nature,\u201d Nerem said. \u201cAs the CEO of an important company, he did not believe in an executive dining room. So he hosted me for lunch in the cafeteria where all the other employees were. That was just his style.\u201d\u003C\/p\u003E\u003Cp\u003EThe connection made then and maintained through the years was instrumental in the formation of the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University.\u003C\/p\u003E\u003Cp\u003E\u0022Walter H. Coulter\u0027s life and approach to work are an inspiration to us all and we try to honor his memory every day in the way we approach our educational and research activities,\u0022 said Steve Cross, Georgia Tech\u2019s Executive Vice President for Research.\u003C\/p\u003E\u003Cp\u003EThis year, Wallace Coulter would have turned 100, and to celebrate the life and scientific legacy of Coulter, his namesake department is hosting a celebration on Dec. 5-6 at Georgia Tech and Emory University.\u003C\/p\u003E\u003Cp\u003E\u201cI have heard many wonderful stories about Wallace\u2019s deep commitment to his team and his people and employees,\u201d said Ravi Bellamkonda, who holds a Wallace H. Coulter Chair in the department. \u201cI\u2019d like to think that the Coulter Department has a similar environment of a team and a family.\u201d\u003C\/p\u003E\u003Cp\u003ECoulter studied electronics as a student at Georgia Tech in the early 1930s. The Coulter Foundation, through its philanthropy, helped establish the innovative academic department operated jointly by Georgia Tech and Emory University.\u003C\/p\u003E\u003Cp\u003E\u201cThere\u2019s no question that the major gift by the Coulter Foundation was extremely important in building the biomedical engineering department to propel itself in a very short time to being a leading department in the country,\u201d said Don Giddens, the founding chair of the Coulter Department and former dean of the College of Engineering.\u003C\/p\u003E\u003Cp\u003EThe biomedical research conducted today might not be possible without the invention of the Coulter Counter. The Coulter Counter transformed diagnostics in hospitals by allowing rapid counting of blood cells. As cells of different sizes go through the counter, the cells change the current that flows through the device. That change in current is used to very rapidly count blood cells, providing information that helps spot illnesses in patients.\u003C\/p\u003E\u003Cp\u003EThe invention of the Coulter Counter was the foundation for the successful, multi-national Coulter Corporation. Wallace Counter also held 85 patents and positioned the Coulter Corporation as a leader in the diagnostics technology industry. In October 1997, the Coulter Corporation was acquired by Beckman Instruments, Inc. and the company is now known as Beckman Coulter, Inc.\u003C\/p\u003E\u003Cp\u003E\u201cI will always remember the Coulter Counter as the best way to count cells without having to do it by eye and on a microscope that can be prone with many different errors,\u201d said Manu Platt, an assistant professor and GRA Distinguished Cancer Scientist in the Department of Biomedical Engineering, who also earned his PhD in the Coulter Department. \u201cFor it now to be so routinely done in hospitals has allowed for greater processing of a large number of patient blood draws.\u201d\u003C\/p\u003E\u003Cp\u003EAnalysis of blood work revolutionized the detection of cancer and many kinds of blood-related diseases. Tests that once took several days took just minutes with the Coulter Counter.\u003C\/p\u003E\u003Cp\u003E\u201cWallace Coulter firmly believed that technology and engineering can change medicine for the better,\u201d Bellamkonda said. \u201cThat is entirely our focus here in the Coulter Department of Biomedical Engineering.\u201d\u003C\/p\u003E\u003Cp\u003EOutside of biology, the Coulter Counter has had commercial impacts in other fields such as manufacturing. For example, the Coulter Counter is used in paint manufacturing to quickly measure particle size and number.\u003C\/p\u003E\u003Cp\u003EThe Coulter Counter was based on the Coulter Principle, which says that when cells are passed through microchannels separating electrolyte solutions, a transient current drop is proportional to the particle volume.\u003C\/p\u003E\u003Cp\u003EThe Coulter Principle is one of the precursors to microfluidic studies that are commonly used today, Platt said.These studies are now at the forefront of how to miniaturize or \u201cnano-ize\u201d diagnostic detection devices for cheaper, faster and better assays, which are directly applicable to\u0026nbsp; environments like those in developing countries, such as in rural Africa where Platt does fieldwork studying HIV\/AIDS.\u003C\/p\u003E\u003Cp\u003EMicrofluidic studies, such as Assistant Professor Todd Sulchek\u2019s work sorting cells by stiffness to spot disease, are a modern legacy of the Coulter Counter.\u003C\/p\u003E\u003Cp\u003E\u201cThat principle \u2014 the idea of making a very small aperture or very small hole \u2014 is a foundation for microfluidics,\u201d said Sulchek, who works in both the Coulter Department and the George W. Woodruff School of Mechanical Engineering. \u201cPeople realized that if you make very small dimensions, on the scale of individual cells, you can utilize new mechanisms for detection. That idea underpins almost all of microfluidics.\u201d\u003C\/p\u003E\u003Cp\u003ECoulter was driven to innovate, something that the Coulter Department also strives for. Many of the Coulter Department\u2019s faculty members have created startups and are interested in taking their ideas further. They are not satisfied with just publishing a study, Bellamkonda said. Embedded in the DNA of the Coulter Department is a drive to move technologies to patients as fast as possible, he said.\u003C\/p\u003E\u003Cp\u003EJust one example of this drive is found in the Cardiovascular Fluid Mechanics lab of Ajit Yoganathan, the Associate Chair for Translational Research, Regents Professor and the Wallace H. Coulter Distinguished Faculty Chair in Biomedical Engineering. His lab has a rich history of translational research over the past 34 years, working closely with cardiologists and cardiac surgeons, both adult and pediatric, to identify the important questions and challenges that the clinicians face and how the lab\u2019s research could help clinical care.\u003C\/p\u003E\u003Cp\u003EYoganathan\u2019s lab has developed a repair technology for the mitral valve that is currently licensed for commercialization to a major heart valve company, and the lab has also developed a minimal blood loss access port into the left ventricle, which is in clinical trials in partnership with his startup company Apica Cardiovascular.\u003C\/p\u003E\u003Cp\u003E\u201cThe ideas came from basic research that was going on in the lab and having the Coulter funding allowed us to take it to the next level,\u201d Yoganathan said.\u003C\/p\u003E\u003Cp\u003EHelping improve the lives of patients through commercializing biomedical research is a modern-day Coulter principle.\u003C\/p\u003E\u003Cp\u003E\u201cThe old Coulter principle is how to count particles. The new Coulter principle, pioneered with single-minded focus by the Coulter Foundation, is helping us take engineering innovations from the lab and successfully commercialize them,\u201d Bellamkonda said. \u201cWallace\u2019s legacy vibrantly lives on through the work of his foundation.\u201d\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EResearch News\u003Cbr \/\u003E Georgia Institute of Technology\u003Cbr \/\u003E 177 North Avenue\u003Cbr \/\u003E Atlanta, Georgia\u0026nbsp; 30332-0181\u0026nbsp; USA\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: Brett Israel (404-385-1933) (\u003Ca href=\u0022mailto:brett.israel@comm.gatech.edu\u0022\u003Ebrett.israel@comm.gatech.edu\u003C\/a\u003E) or John Toon (404-894-6986) (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E)\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Brett Israel\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDecember 5, 2013 - Wallace H.
