The Biomedical Computing and Visualization Lab at UMass Lowell focus on analyzing data in Biomedicine for enabling data-driven decision making in medicine, health care, and brain science. Our group tackle data science with three research components:

  1. Computational Solutions and Machine Learning - To understand how data is structured, analyzed and processed through data modeling, information retrieval and data-intensive computing.
  2. Scientific Visualization - To explore how we can make sense of our big data sets combining multi-dimensional information obtained in various format and imaging modalities.
  3. Interactive User interfaces - To discover how interaction with the data at multiple scales can help us connect the dots and can lead to new knowledge.

These three research components interact with one another to expand our knowledge in computer science, brain and health sciences. We believe that application-driven contributions to expand computer science to interdisciplinary research will become more and more important in exploring and understanding scientific and health-related problems.

Our current projects span the following research areas:

  • Computational Drug Design and Repurpose: when quantum mechanics meets machine learning
  • Brain Disease Biomarker: quantitative microstructure extraction from diffusion MRI
  • Interactive Multidimensional Brain Visualization: understanding and connecting brain data at multiple scales

Computational Language Understanding (CLU) Lab

Lab Director: Hadi Amiri
Location: Southwick Hall 320
Phone Number: 978-934 3612
Computational Language Understanding (CLU) Lab
The Computational Language Understanding (CLU) Lab is principally concerned with advancing computational models to understand the semantics of human language and translating these models into clinical practice. Our approach is to seek a good understanding of human language, to capture the essential features of language in appropriate models, and to develop the necessary computational framework to advance knowledge and discovery in Natural Language Processing (NLP) and Healthcare. We accomplish this through rigorous computational research coupled with partnerships with linguists and clinicians.
Several specific areas that we are currently investigating are listed below:
  • Curriculum Learning for Natural Language Processing: Deep neural networks can effectively tackle many NLP tasks, but they could be computationally expensive to train. How can we uncover the salient characteristics of these learners (networks) and their learning materials (training data) for effective representation of textual data and efficient training?
  • Clinical Decision Support: Most medical information, from physician notes to referral letters to scientific articles, are locked in unstructured text and are not readily accessible. NLP and Machine Learning techniques offer potential means to support clinicians with evidence and insight extracted from such data. What are the best techniques to represent multimodal patient data and reference materials about diseases, triage patient applications, pinpoint disease-causing gene variants, and enhance clinical decision support systems with evidence?
  • Social Media Surveillance: User generated content in social media present naturally occurring data that can be used to obtain low-cost and high-resolution views into population behavior. How can we develop online surveillance systems that can monitor population behavior at scale to detect (health-related) trends and (disease) outbreaks, and identify opportunities for decision making, resource allocation or intervention?
The CLU Lab hires undergraduate UROC scholars (including Immersive), who can play a significant role in all aspects of our research. If you are interested in a UROC position, please visit the Opportunities page. We are happy to work with students who have successfully completed relevant courses and have a good proficiency in a programming language. Exposure to Natural Language Processing, Machine Learning or Artificial Intelligence toolkits is a bonus. We also accept resumes from graduate students who have a passion to conduct research in NLP. For more information on the members and current research of the lab visit Hadi Amiri's page or the website of the Computational Language Understanding (CLU) Lab.

Text Machine Lab for Natural Language Processing

Lab Director: Anna Rumshisky
Location: Dandeneau Hall 415
Text Machine Lab website

The Text Machine Lab at UMass Lowell conducts research in machine learning applications for natural language processing, with a focus on deep learning methods. Our current projects span the following research areas:

  • Computational lexical semantics, distributional analysis and machine learning techniques for representing lexical and sentence-level meaning
  • Text-based temporal reasoning, argument mining
  • Clinical natural language processing, including information extraction, and predictive modeling using clinical patient records
  • Digital knowledge and sentiment tracking for digital humanities and social science

The Text Machine Lab generally hires undergraduate students and Ph.D. students; MS students are only hired in exceptional conditions (e.g. they have done NLP/ML before coming to UMass Lowell). If a student wants to get involved with this lab, they should take machine learning, and learn some PyTorch; Andrew Ng's online course or the machine learning course here at UMass Lowell are both good starting points. Once you reach out and express your interest to the lab director, you’ll typically receive some good exercises to code up in order to get up to speed.

For an extensive list of projects, papers, and students who have been products of this lab, please check out the lab’s website! The TwitterHawk project was led by an undergrad.

“One thing I can say is that the undergraduate students that join my lab get involved in research early. I believe there are plenty of very talented undergraduates at UMass Lowell who should be given a chance to participate in research and given a chance to contribute meaningfully -- and unfortunately, that often does not happen until they get to their senior year. I try to do the opposite and give people challenging things to work on early on. As a result, I have undergraduate RAs who by the time they graduate have had more research experience that many first or second year Ph.D. students. Typically, undergraduates in my lab publish papers at major conferences and come out well prepared -- the very first of my undergraduate research assistants ended up receiving the NSF Graduate Fellowship and he is currently finishing his Ph.D. at MIT EECS.”

Text Mining and Document Engineering Group

Lab Director: Jie Wang
Location: Dandeneau Hall 408
Jie Wang's personal website

The group performs research in text mining algorithms and systems, document engineering, and data modeling and its applications. Some of the projects that we have worked on include intelligent text automation, document summary, domain extraction and statistical measurement in knowledge networks, and news classification.

The Text Mining and Document Engineering Group hires Ph.D. students and occasionally master’s students. However, they do plan on hiring undergraduates in the future.

Linear reading from the beginning to the end is the normal way of reading for the purpose of learning new knowledge. Is there a better way to read for understanding? Let’s think outside the box and turn linear reading to hierarchical reading. Imagine that we have access to an oracle that ranks the sentences of the given text according to their importance, allowing us to read blocks of sentences one at a time in descending order of importance, focus on the most important block of sentences, and read subsequent blocks to strengthen understandings of earlier blocks. Moreover, the oracle also generates questions and evaluates answers. Dooyeed is an AI-assisted text mining system to facilitate reading for understanding to meet the AEE requirements: Accurate and Efficient for the oracle and Effective for the reader. Dooyeed outperforms each individual human judge over the SummBank benchmarks and compares favorably with the combined rankings of all judges. Dooyeed currently supports two major languages: English and Chinese. This invention is made by Jie Wang and assisted by his Ph.D. students, Students who have participated in the research and development of Dooyeed include Cheng Zhang, Hao Zhang, Changfeng Yu, Yicheng Sun, and You Zhou. Eola Solutions, Inc. provided financial support.

The Text Mining group has graduated a number of Ph.D. students and MS students, including Yiqi Bai (now at Facebook Seattle), Ming Jia (Facebook Seattle), Liqun Shao (Microsoft Cambridge), Jingwen Wang (Elizabethtown College), and Wenjing Yang (Dell EMC).
