The Department of Computer Science at NJIT boasts a distinguished faculty that embody the university’s commitment to furthering research and technological progress.
Associate Professor and Associate Chair
Did you know that in 2011, the average American commuter spent nearly 38 hours—almost a full work week—stuck in traffic? This constantly increasing congestion comes with a high cost. From lost productivity to increased vehicle maintenance to higher gasoline bills, there’s no question that the daily commute is taking its toll on today’s travelers.
Imagine this: you’re on the road to work, and you open a mobile application that pinpoints your exact location in relation to current congestion along your route. It then provides you with alternative, time-saving directions meant to help you avoid traffic jams completely. Sound too good to be true? Not according to Dr. Cristian Borcea.
“It’s great to conceptualize and theorize new ideas,” Borcea says. “But it can’t end there. Innovation requires implementation; ideas must one day become viable prototypes, and that’s exactly what we deliver at NJIT.”
An associate professor at NJIT, Dr. Cristian Borcea has built a smart application that utilizes the GPS sensors in smartphones to track driver location and relay real-time information regarding road conditions. It uses data collected from drivers to offer alternate—and less congested—routes to their final destination. Widespread use of the application could ultimately result in faster, safer commutes for American drivers.
Eric Schmidt, Google’s executive chairman, estimates that every two days, we create as much data as we did from the dawn of civilization through 2003.
In today’s hyper-connected digital world, user-generated content is exploding. From Facebook profiles to personal blogs, people are putting more information online than ever before, and modern enterprises couldn’t be happier about it. Why? Because every time we swipe our debit card, visit a website, or post a picture to Instagram, we’re leaving behind a trail of raw data that’s ripe for collection. On its own, this raw data is virtually useless, but it does contain valuable insights about the person who created it. In other words, welcome to the specialized field of data mining and analysis—a particular area of expertise for Dr. Vincent Oria.
“We use mathematical models—or recommendation algorithms—to glean knowledge from data,” Oria says. “In doing so, we can generate a list of recommendations based on an individual’s patterns of behavior.”
These recommender systems have transformed the way in which online retailers market to their customers, and continuous improvement of these applications drives Oria’s current research. He’s building the next generation of these systems—focused on finding new methods to improve accuracy.

How many ways do you use your smartphone or tablet? They serve as cameras, calendars, alarm clocks, and road maps. As a society we’ve become ever-more reliant on mobile technologies in everyday life.
With all that mobile technology offers today, what innovations are on the horizon?
Imagine a smartphone that can gather real-time information and suggest alternate routes to help you avoid traffic congestion. Think of the lives that could be saved if your phone could wirelessly interface with other vehicles to pinpoint proximity and prevent accidents. These are just a few of the cutting-edge projects on which Dr. Wang is currently working.
A professor at NJIT since 2006, Dr. Grace Wang is driven by the innovative ways in which wireless networks, mobile technologies and sensor networks can be used to improve quality of life. “Sensor networks connect the physical world to the information world,” Wang says. “By aggregating and applying the data collected by these sensors, we can develop smart technologies and other mobile computing devices that can positively impact everything from driver safety to individual health and wellness.”
Chair and Professor
The American healthcare system is undergoing dramatic changes. After recent government mandates initiated the shift from paper to electronic medical records (EMRs), the healthcare industry is now preparing for the next phase of its metamorphosis. Standardized medical terminology systems such as the Unified Medical Language System (UMLS) and the Systematized Nomenclature of Medicine — Clinical Terms (SNOMED CT), both research topics at CS/NJIT, will be of increasing importance in EMRs.
In the healthcare industry, maintaining the integrity of electronically recorded and shared patient data is crucial to quality care. This process relies to some degree on Medical Terminologies. Medical Terminologies are large and complex. Many times, errors, omissions, and inconsistencies are hidden within this complexity. The issue is further complicated by the fact that doctors, lab techs, nurses, and other healthcare professionals often use different terms to communicate the same concept. The work of NJIT Computer Science professor Dr. Jim Geller is helping to shape the field’s future.
Dr. Geller—working with Dr. Yehoshua Perl and other researchers—has developed sophisticated abstraction networks that can be used to track down errant and misplaced medical terms. “The goal of every abstraction network is to summarize a large terminology and to hide overwhelming networks of connections,” Dr. Geller says. “In doing so, we can focus on the big picture and visualize groups of medical terms in a graphic format that is easier to understand and more useful for locating errors.”
Having started in 1988 at NJIT, Professor Geller is an experienced researcher in Computer Science and Medical Informatics. He has authored and co-authored over sixty-five journal papers and more than ninety conference papers on a broad spectrum of topics, from Semantic Modeling in Object-Oriented Databases and Web Mining to Medical Informatics, Medical Vocabularies, and Auditing of Ontologies and Medical Terminologies.
Did you know that the human face is as unique as a fingerprint? It has numerous distinguishable features that can be mapped and measured to establish an individual’s identity—which is exactly what today’s facial recognition technologies are designed to do.
Well, imagine using an ATM that requires facial recognition to authenticate your withdrawal, or visiting a retail store that utilizes a pay-by-face system at checkout, or passing a billboard that scans your face to deliver gender-specific ad content. According to Dr. Chengjun Liu, these are just a few of the many ways in which we could see facial and biometric recognition technologies used in our lifetime.
“Whether you realize it or not, the age of facial verification has already begun,” Liu says. Facebook now offers facial recognition as a default feature to tag photos and find friends. Android phone users can utilize a facial recognition application to unlock and access their device. Even the FBI is deploying a new system that integrates facial and biometric recognition into its existing identification databases.
Improving the future of facial recognition technology is the main focus of NJIT Associate Professor Dr. Chengjun Liu’s work. Through research funded by the U.S. Department of Defense, Liu has successfully developed a new, more efficient recognition system that can recognize changes in the environment, lighting, expressions, and even age to match faces with unprecedented accuracy.
It is in some sense quite groundbreaking, and sometimes I think it’s also the primary breakthrough in theoretical computer science of the 21st century. Homomorphic encryption provides a path that would enable victims of cyberattacks to privately share information about the existence of cyberattacks so that we as a society can better defend ourselves from the cyberattacks.
As far as the work that I’m doing on fully homomorphic encryption, is in some sense quite groundbreaking, and sometimes I think it’s also the primary breakthrough in theoretical computer science of the 21st century.
For a long time people would use encryption technologies to protect their data. The data come once the data is actually encrypted, you would be able to give it to someone – say as a cloud host or someone else – where that cloud hose can pull the data for you. But if the data was encrypted, the host would not really be able to do much with the data, other than give it to someone else. With homomorphic encryption, it’s a way of encrypting a set of data so no one can touch it, no one gets access to it. But then you can give the encrypted data to someone you don’t necessarily trust – like the Amazon cloud – and then run computations on the encrypted data without sharing keys, without giving any access to the encryption to the cloud host. That cloud host would run a computation on the data, get an encrypted result, give the result back to you. You could then decrypt that result, and that decrypted result is the same as if you had run the original source computation on the original data without encryption. So in some sense is a fundamental black magic, in that you can actually enable computing on encrypted data. This has tremendous implications for multiple industries, for government, and for the society at-large. Particularly, let’s look at the healthcare industry. In healthcare there are large issues of privacy. All this data is being generated by all these patients at all these hospitals and all these various insurance agencies across the world.
There is very strong both privacy concerns associated with patients not wanting to share that data, and also very strong commercial competitive concerns, where insurance companies don’t want to share information about their subscribers and give their competitors any kind of information about who they are receiving their money from. At the same time, there would be a large benefit if researchers, particularly with funding with the FDA or other agencies, could get access to broader sets of patient data to run computations on those data to compute, for example – what is the most beneficial treatment under certain observed symptoms? Or what is the most effective drug to prescribe to a patient under certain symptoms to maximize patient outcomes, minimize patient death, and for overall betterment of patient health? The trouble with this though is because the patient, because the insurance companies, because the hospitals have these very strong privacy concerns – and very valid privacy concerns – they’re less willing to share the data. With homomorphic encryption, we provide a way – if enabled – were patients, doctors, insurance agents could encrypt data, share the data, and enable competitions on this data to better provide better healthcare for their patients. The trouble with homomorphic encryption nowadays though is although it’s been demonstrated to be theoretically feasible, it is still not completely practical.
Technology is synonymous with progress, and for 130 years, the New Jersey Institute of Technology has been an institution on the move. In the last decade, we’ve doubled the size of our campus and poured millions into new research facilities to give our students the edge they need in today’s technological marketplace.

The story of the New Jersey Institute of Technology began during a time of unprecedented growth in America. Imagine Newark, New Jersey, in the midst of tremendous industrial and population growth. It was the late 19th century, and the “The Gateway City” was quickly becoming a bustling hub for manufacturing and shipping. Thomas Edison had set up shop on Ward Street. His rival in the development of electricity, Edward Weston, had built the first factory in the United States for the commercial production of dynamo electric machines, and the demand for highly skilled labor with technical expertise was growing exponentially.
In 1880 the New Jersey state legislature introduced “An Act to Provide for the Establishment of Schools of Industrial Education.” Sponsored by the Newark Board of Trade, the act established three schools of industrial education. The Newark Technical School opened its doors four years later on Monday, February 9, 1885, with 88 students. Over the next half-century the school’s development continued until in 1949 the Newark Technical School was formally transformed into the Newark College of Engineering.
During the Great Depression and World War II, enrollment and expansion slowed, but the post-war period brought a time of immense activity when the university’s president challenged the college to turn “war-time thinking into peace-time thinking.” Campus expansion continued, and the first doctoral level programs were introduced. With the addition of the New Jersey School of Architecture in 1973, the institution had fully evolved into a technological university. The program offerings emphasized a wide range of graduate and undergraduate degrees, and the dedication to providing the region and the world with significant research and public service grew stronger.
Under the leadership of former president Saul K. Fenster, NJIT’s focus on education expanded to include research, the economic development of Newark and New Jersey, and public service. Since the mid-1970s NJIT has become home to nearly 50 laboratories, centers, and business incubators, resulting in hundreds of breakthroughs, such as new methods for producing carbon nanotubes, techniques for monitoring the earth’s climate using measurements of earthshine, approaches to use membrane separation technology to desalinate water, and algorithms for wireless telecommunications and signal processing. Research funding has surged to more than $75 million and promises to keep rising.
In the words of President Joel S. Bloom, “As a school focused on science and technology, NJIT has always had a connection with the private and public sectors. Newark Technical School was founded to forge this connection in its home city. Significant change now under way at NJIT will add a new dimension to our economic engagement and the manner in which students are prepared for productive careers. While research is of paramount importance at NJIT, we are equally dedicated to providing talented young women and men with the knowledge and skills needed for personal achievement and for the prosperity of our nation. We are bringing more talented people and greater resources together at NJIT to ensure that success will continue for the graduating classes to follow.”
At NJIT, our focus is to grow the reach and scope of our research and continue to be a world leader in progressive sustainability strategies on campus. Our research program is among the fastest growing in the nation, and NJIT ranks among the top ten technological universities in the nation for research expenditures. University researchers continually seek new knowledge to improve processes and products for industry and our world as a whole. NJIT computer scientists pioneered the Virtual Classroom® and developed the first software to support distance education. This precursor to online education proved the effectiveness of this approach and opened the door for widespread adoption when the Internet became a staple in many homes around the world. Through public and private partnerships and economic development efforts, the university helps to grow new business ventures that fuel the economy.
As we move forward, it’s important that, as our student body grows, our campus function as efficiently and independently as possible. Part of NJIT’s Strategic Plan includes the development of sustainable systems, including green construction, the application of environmental science and engineering in design, and alternative energy technologies such as solar cells.
