Geopolymers: The Future of Environment-Friendly Cement–Day Two

By Ishaa Sahani

The second day of Cognizance saw a technical presentation by Ms. Rashmi Singla on the Designing and Characterization of Hybrid Geopolymers. Ms. Singla is a scientist at the Council Of Scientific And Industrial Research-National Metallurgical Laboratory (CSIR-NML) who is currently pursuing her Ph.D. from The Academy of Scientific and Innovative Research (AcSIR) by researching building materials viz. hybrid geopolymers. Ms. Singla graduated from the National Institute of Technology,  Jalandhar with a Bachelor’s in Chemical Engineering in 2014 and then joined CSIR-NML as a trainee scientist. In 2016, she completed her Masters in Material Science and Metallurgical Engineering from AcSIR. She is an awardee of the Marie Sklodowska-Curie Fellowship for the Doctoral Programme. She has four publications and two patents to her name.

The event was attended by over fifty students eager to explore this field. Ms. Singla started the presentation from the very basics of hybrid materials. Hybrid materials have two moieties: organic and inorganic, that are blended into one on a molecular scale. Moieties are parts of a molecule that are identified as building blocks in other molecules as well. Their properties majorly depend on the interactions between the two kinds of phases present in them. Hybrid geopolymers are an example of such hybrid materials, in which favorable properties can be developed due to the high strength and environmental-friendly nature of geopolymers.

Her research focuses on tailoring the interaction between the two phases to get desirable properties. As a result, the samples show higher compatibility between the organic and inorganic phases, resulting in a higher compressive strength than ordinary geopolymers.

Upon conclusion of the presentation, a few curious minds raised some insightful questions about the various feasible applications of geopolymers, to which Ms. Singla explained that geopolymers mainly find use in structural and construction purposes, though currently, we do not have any technology to produce geopolymers on a commercial scale. Geopolymers are an emerging technology and the growing worldwide demand for concrete presents huge possibilities in the future for the development and large-scale use of geopolymers.

ABCDs of Drug Discovery–Day Three

By Arshia Puthran

On 20th July, Dr. Subrahmanyam Vangala took a ninety-minute-long session explaining comprehensively the revolutionary changes that drug discovery has undergone over the years. The CEO and co-founder of Reagene Biosciences located in Bangalore, Dr. Vangala is a Biochemistry Ph.D. graduate from Memorial University. He then continued his post-doctoral training at the University of Toronto, University of Colorado, and University of California at Berkeley. With a background of working in the pharmaceuticals industry for 30 years, his company revolves around pioneering new medications for many of the diseases inflicting the human race. His talk provided extensive insights into drug discovery, breaking down the entire process of the development and trials of drugs and outlined the challenges faced during the manufacturing of the same.

Dr. Vangala began his presentation by detailing the two criteria set by regulatory agencies for the drug to be approved to be sold in the market – efficacy and safety. The companies receive a green light when the benefits outweigh the risk. The typical strategy to select drugs is based on different clinical trials, which are colour-coded using red, yellow, and green. The prominence of green indicates success and the medicine gains validation.

He followed this by discussing the major illnesses in today’s world compared to the past, owing to the lifestyle changes of society, with ischemic or coronary heart disease being the leading cause of death currently. The industry has been victorious in developing antibiotics, medicines for diabetes, and many other common sicknesses, however, drugs for degenerative diseases persist to cause problems.

The discovery of novel drugs comprises a 5-step process to filter out 1 or 2 out of the 10,000 drugs that go through the procedure. With an enormous expenditure of $2.5 billion over 10-14 years with zero assurance of its success as NDA does not tend to easily give its stamp of approval, drug research can be a huge financial liability involving many risks.

Dr. Vangala then elucidated the drastic changes observed during the drug discovery process due to technological advancements achieved by the science sector. He took the audience on a journey from the 1960s to the 2000s, describing thoroughly the application of the new knowledge gained over the years and its effect on the rate of novel drugs approved. The 1990s particularly saw a rise in drug toxicity in humans, due to animals being unaffected by the poison during clinical trials, which then led to the startling revelation that animals and human interactions with drugs differ and thus cannot be used to accurately predict its safety and efficiency.

The intricacies of the human body have proven to be a barrier for the drug development industry since time immemorial, due to the many equations regarding genes, proteins, epigenomes, and metabolomes that remain unsolved. The complexity of genes has boggled professionals, with new factors affecting the gene composition being discovered regularly, including and not limited to ethnicity diversity and age.

He shared anecdotes about his friend while explaining about drugs being withdrawn due to hepatotoxicity and cardiac toxicities, who was involved with the issues relating to the drug Troglitazone, removed from the market for hepatotoxicity. Moreover, he went onto explain in detail how orally administered drugs work, the various interactions that take place inside the body on ingestion, and the changes that occur in the blood composition. He related everything he taught during the talk to the current unprecedented situation of Covid -19, which definitely helped better comprehend the entire drug discovery process and challenges that follow it.

Dr. Vangala concluded his talk with a quote from Steve Jobs – “Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn’t really do it, they just saw something.” The session came to a fulfilling end with an enthusiastic QnA discussion, with intriguing questions from the students and enlightening answers from the speaker.

A Well-Spun Tale of Electronics–Day Four

By Paridhi Gupta

On 23rd July, the sixth day of Cognizance, Mr. Rahul Mishra, an assistant professor in the Center of Research for Applied Electronics at IIT Delhi was invited. He presented an elaborate session on the intriguing topic of “Spintronics and Its Future Scope” on Microsoft Teams.

Mr. Mishra has a Ph.D. in Electrical and Computer Engineering. He was a graduate student at the National University of Singapore, where he went on to complete his post-doctoral research. He completed his Btech/Mtech dual degree from IIT Kanpur and worked as a component design engineer for Intel. Rahul is also a recipient of various national and international level awards and recognition, such as the President’s Graduate Fellowship from NUS and the Academic Excellence award from IIT Kanpur. He has over 19 published papers in the field of Spintronics and over 690 impressive citations.

Rahul Mishra explaining the Why? of spintronics

Spintronics is a field of study in electronics focusing on the spin or angular momentum property of an electron and the fundamental electronic charge in solid-state devices. This spin in electrons gives rise to magnetization, which is used to store data. Rahul spoke about the history of Spintronics and later discoveries, and its various applications in the data storage of electronics devices. He explained the need for Spintronics for the upcoming future generation by displaying the effect of processor frequency, power density, processor performance, and processor-memory gap over the decades and further describing the various features of Spintronics that make it advantageous.

Spintronics is employed majorly in computing memory. With the founding of the “magnetic tunnel junction”—the unit of spintronic memory created by Nobel laureate Michel Jullière, Rahul explained the three different generations of MRAMs used ever since. The session concluded with an insightful QnA session.

Xplaining XAI–Day Five

By Arushi Gandhi

As part of the sixth talk of cognizance event, RSM invited Fatemehsadat Mireshghallah to present her field of research. She is a Ph.D. student at the CSE department of the University of California San Diego. Her research interests are Trustworthy Machine Learning and Natural Language Processing. She is a recipient of the National Center for Women & IT (NCWIT) Collegiate award in 2020 for her work on privacy-preserving inference, and a finalist of the Qualcomm Innovation Fellowship in 2021. She has interned twice at Microsoft Research’s Language and Intelligent Assistance group, where she works on private training of large language models.

A major focus of her talk was about Explainable Artificial Intelligence (XAI) and its impact on Privacy. Explainable AI is artificial intelligence in which the results of the solution can be understood by humans, i.e. an interpretable output. The key axes of operation in an AI processing model are its utility and interpretability. An elegant, well-integrated AI system would ensure both, but increasingly the security of an AI system and the privacy of the data it works with have become sensitive points open to attack. Fatemeh highlighted the privacy-utility-interpretability trade-off that exists within this domain and its impact on the fairness of predictive models. She also discussed risks and certain attacks which could be implemented on Natural Language Processing (NLP) models and how privacy could mitigate it.

The session had an impressive turnout for an online event with about 85 people who showed up for the event. An attendee, Vedant Rishi Das asked, “With all of our information already online, do you think privacy-preserving machine learning will add to leakage accountability by these companies or social media platforms?” To that, Fatemeh pointed out the increasing number of lawsuits that companies are having to face, which will lead to companies being forced to take accountability. That being said, people need to take caution with respect to the sort of content and personal information they put out on the internet.

The moderator of the event, Aman Priyanshu ensured smooth running and had some great concluding thoughts— “Privacy is an important aspect of every person’s life. Introducing this concept into the field of machine learning will allow trustability and accountability”.

The final session on Physics was also cancelled due to unavoidable circumstances.

Despite three of the nine sessions being cancelled, Cognizance was a huge success. Each day boasted of impressive turnouts, acclaimed speakers, and enthusiastic participants. RSM came up with yet another immensely educational event,  exposing MIT students to exciting fields previously unexplored.
