Biography

Murthy Devarakonda's educational background is in computer science. He received his doctorate in computer science from University of Illinois at Urbana-Champaign. All of his professional experience until joining ASU was as a research scientist and as a team manager at IBM Research, Yorktown Heights, NY.

Devarakonda was a member of the well known IBM Watson team (who created IBM Watson that defeated two legendary champions in a televised Jeopardy! quiz show in 2011). He joined the team after the televised event in 2011 and through 2017, he was the lead and the team manager for an initiative to apply IBM Watson methodology to longitudinal patient records, especially concentrating on the textual narratives of the patient records. They worked with patient records and physicians from multi-specialty hospitals, developing natural language processing and machine learning methods for automatically extracting insights such as the problem list from the text narratives of a patient record.

Prior to the IBM Watson tenure, Devarakonda's research was mainly in distributed computing systems where he applied data science (before it was called by that name) to identify insights from measurement data and to use the insights as foundational elements to develop novel algorithms and distributed systems.

Devarakonda is a fellow of the Institute of Electrical and Electronics Engineers (IEEE), and a distinguished member of the Association for Computing Machinery (ACM). He received an Outstanding Technical Achievement Award, a Master Inventor award, and several Research Division Awards at IBM. He's published more than 60 refereed papers in conferences and journals. He's also received 42 patents for the work at IBM Research.

Research Activity

My current research interests are in exploring natural language processing (NLP) and machine learning for medical and clinical applications. A large portion of a patient record is clinical narratives, known as clinical notes, written by care providers such as physicians and nurses. The clinical notes include information about the patient and their treatment beyond what is included in the structured and coded data, and so it's a gold mine for knowledge and patient care insights. Novel NLP methods can unlock the value from the patient records by improving efficiency and effectiveness of care providers. treatment processes, adverse drug reactions, and drug repurposing to name a few.

The number of publications and clinical trial data is increasing at an exponential rate, and novel methods are needed to bring this information to physicians, researchers, policy-makers, and patientsin in a usable form. Social media including blogs and tweets are another great source of insights into patient care and outcomes. Internet of Things (IoT) devices collect large quantities of data about us, often unitrusively and without participant awareness,  which can provide new insights into individual and group health, when combined with patient health records. My research explores these sources of data for deep insights useful in health and wellness care.

Exciting new advances in neural networks methds for NLP accelerate the process of extracting insights from vast medical and clinical text sources. A growing number of tools available to use the new methods offer a low-barrier to entry in applying the novel methods. Increasing availability of low cost cloud computing and GPU technology provides the necessary computing platforms for the adavced methods. My research includes exploring these foundational aspects for improved healthcare.
