Biography
Ashok Krishnamurthy, PhD, came to RENCI in January 2013 from the Ohio Supercomputer Center (OSC), where he served as director of research and scientific development.
Dr. Krishnamurthy was also an associate professor in the computer and electrical engineering department at The Ohio State University and served as OSC co-interim executive director from September 2009 to August 2012.
As deputy director of RENCI, he is responsible for managing and enhancing research partnerships with faculty at UNC Chapel Hill, Duke University, and North Carolina State University; building relationships between RENCI and Triangle area businesses; and leading efforts to bring new federal research funding to RENCI and its partner institutions. He is known for working successfully with stakeholders involved in university-based technology research organizations, including faculty researchers, administrators, funding agencies, government, and the business sector.
Dr. Krishnamurthy worked closely with Dr. Stan Ahalt, RENCI’s current Director, during his tenure as OSC executive director (2004 – 2009) and played a crucial role in establishing OSC’s successful industrial outreach initiative, Blue Collar Computing. Before his work at OSC and OSU, Dr. Krishnamurthy served as the academic lead for the U.S. Department of Defense (DoD) High Performance Computing Modernization Program in the Integrated Modeling and Test area. He has designed and provided numerous training courses for DoD User Groups on all aspects of the MATLAB programming language.

"Both of OSC's two most recent flagship computing systems were specifically designed to support biomedical applications, such as those employed by Dr. Erdemir and Mr. Sibole," said Ashok Krishnamurthy, OSC interim co-executive director. "Researchers working at Ohio's various respected medical centers are conducting an ever-increasing load of computational studies and analyses, and they now represent a significant share of our user community."...

"For many years, Ohio industry has invested heavily in the aviation, aerospace and manufacturing sectors, which naturally led OSC to focus a portion of its computational resources on the field of advanced materials," said Ashok Krishnamurthy, interim co-executive director of the center. "Dr. Garafolo's work is an excellent example of how modeling and simulation often allows scientists to analyze materials in ways not possible through simple observation or physical experimentation."...

The center is working harder to get that secret out, said Ashok Krishnamurthy, interim co-executive director and senior research director. As well as expanded marketing efforts, the center now can set aside even more computing power for private industry. It took delivery Dec. 28 of $4 million in servers and processors, replacing half the supercomputer’s brain while providing 1.5 times the computing capacity with 40 percent less power consumption...

Variability in the production of quantal vowels revisited
The Journal of the Acoustical Society of America
1995 ABSTRACT: Articulatory and acoustic variability in the production of five American English vowels was examined. The data were movement records for selected fleshpoints on the midsagittal tongue surface, recorded using the x‐ray microbeam. An algorithm for nonlinearly transforming fleshpoint positions to a new Cartesian space in which the x and y axes represent, respectively, the distance of the fleshpoint along the opposing vocal tract wall and the distance perpendicular to the tract wall, is described...
Competitive learning algorithms for vector quantization
Neural Networks
1990 ABSTRACT: We compare a number of training algorithms for competitive learning networks applied to the problem of vector quantization for data compression. A new competitive-learning algorithm based on the “conscience” learning method is introduced. The performance of competitive learning neural networks and traditional non-neural algorithms for vector quantization is compared...
Neural networks for vector quantization of speech and images
IEEE Journal on Selected Areas in Communications
1990 ABSTRACT: Using neural networks for vector quantization (VQ) is described. The authors show how a collection of neural units can be used efficiently for VQ encoding, with the units performing the bulk of the computation in parallel, and describe two unsupervised neural network learning algorithms for training the vector quantizer...
Two-channel speech analysis
IEEE Transactions on Acoustics, Speech and Signal Processing
1986 We present a two-channel technique for improving speech analysis in certain applications. One channel is the signal from an electroglottograph (EGG), which monitors the vibratory motion of the vocal folds. The other channel is the speech signal obtained from a conventional microphone...
A critical review of electroglottography
Critical Reviews in Biomedical Engineering
1985 ABSTRACT: The technique of electroglottography is reviewed from the perspective of a laboratory instrument for assessing laryngeal function, a device to assist speech and speaker recognition, and as a potential diagnostic aid in the clinic. A description of the electronic functioning of the electroglottograph (EGG) is provided...
