His autobiography:

I am an Associate Professor of Medicine, in the clinician-educator track and Director of the HIV Clinical Trials program of the Yale AIDS Program, Section of Infectious Diseases of the Yale School of Medicine.

My clinical responsibilities include educating and training medical students, residents and infectious diseases fellows in various capacities in inpatient and outpatient settings; and through structured course work and other teaching sessions.

As a faculty of the HIV training track of the Yale-Internal Medicine primary care program and for over 6 years as a faculty of the Human Resources for Health program in Rwanda, I have extensive experience with curriculum development, structuring of residency training programs, and mentoring residents and faculty.

In Rwanda specifically, I have and continue to mentor medical residents and junior faculty in quality improvement and clinical research projects that are locally relevant and addressing important infectious diseases-related problems (particularly HIV/AIDS and antimicrobial resistance).

Furthermore, I have facilitated meaningful educational and research collaborations between faculty and trainees across institutions.

As the program director of World Bank and HRSA-funded efforts supporting the Liberia College of Physicians and surgeons (LCPS)–run Internal medicine residency training program, I have overseen the selection and deployment of faculty to Liberia, and am responsible for educational programs and activities aimed at strengthening the residency training program.

Overall, my expertise and collective experiences to date have positioned me to design and run successful projects around capacity building in low-resource settings including developing and implementing innovative and robust medical training and research programs for faculty, fellows, residents and students.

For 5 years now, I have been the Director of the Yale AIDS Program HIV clinical trials program, and a principal investigator on numerous pharmacokinetic, phase 2 and 3 safety and efficacy trials of novel antiviral compounds (HIV).

More, recently, given the alarming rate of new infections among men who have sex with men (MSM), I have focused on HIV prevention trials including being a co-principal investigator on a Yale CIRA funded project, which has supported the formation of a cohort of men who have sex with men, who are at high risk for HIV and are engaged in HIV PrEP services in order to study the impact of substance use on retention in care and adherence to PrEP. I am also a lead investigator on the international DISCOVER trial evaluating TAF/FTC vs TDF/FTC for HIV prevention among MSM and transgender women.

In response to the COVID pandemic, I am Yale principal investigator on multiple investigational therapeutic and preventative clinical trials for COVID-19 including remdesivir (now FDA approved), leronlimab and remdesivir and tocilizumab combination therapy as well as the Pfizer/BioNTech Vaccine trial.

Kaspersky, AFRIPOL Conduct Joint Cybersecurity Training for African law Enforcement

Published

Kindly share this post

As part of a joint initiative with AFRIPOL, Kaspersky provided cybersecurity training courses for law enforcement representatives from 23 African countries, unfolding the fundamentals of Security Operations Center (SOC) activities and advanced threat hunting techniques.

As cyberthreats continue to grow in scale and complexity, strengthening the technical capabilities of law enforcement agencies has become an important priority worldwide. Through knowledge-sharing programmes, technology companies can contribute practical expertise gained from real-world cyber investigations and threat analysis.

Such collaboration helps equip law enforcement professionals with the skills and tools needed to investigate digital crimes more effectively and strengthen cybersecurity capabilities.

From November 2025 to March 2026, around 40 African officers from 23 countries* received “Security Operations and Threat Hunting” training, provided as part of the cooperation agreement between Kaspersky and AFRIPOL signed in 2024. During the training, African officers gained practical knowledge of Security Operations Center (SOC) activities and modern cyber-defence practices.

The programme covered key aspects of threat detection and incident investigation, including how to identify malicious activity in Windows and Linux environments, analyse attacker tactics, techniques and procedures (TTPs) and use threat intelligence to uncover advanced threats.

As part of the training, a series of online Q&A sessions were organised, providing participants with the opportunity to engage directly with experts and course authors from Kaspersky’s Security Services team. These sessions allowed attendees to clarify complex topics, discuss practical cases and receive additional insights, reinforcing the learning experience and ensuring a deeper understanding of key cybersecurity concepts.

“Cybercrime today is highly sophisticated, borderless and constantly evolving, which means no single organisation can tackle it alone. This is why cooperation and knowledge sharing between the private cybersecurity sector and law enforcement agencies are so critical. Our long-standing collaboration with AFRIPOL demonstrates the value of this approach.

“Over the years, Kaspersky and AFRIPOL have worked together to better understand the cyberthreat landscape across Africa and to support international efforts aimed at disrupting cybercrime. By continuing to invest in training and capacity building, we aim to support law enforcement professionals with the expertise they need to investigate digital crimes effectively and contribute to building a safer and more trusted digital environment for everyone,” says Yuliya Shlychkova, Vice President, Public Affairs, at Kaspersky.

“Strengthening the capabilities of law enforcement agencies is essential to effectively address the growing complexity of cybercrime across the African continent. Initiatives such as this training programme play an important role in equipping officers with the practical skills needed to investigate cyber incidents, analyse digital evidence and respond to emerging threats.

“Cooperation with partners from the private cybersecurity sector, such as Kaspersky, helps law enforcement agencies stay informed about the latest threat trends and investigative approaches.

“We highly value this collaboration and the opportunity it creates to further develop the cybercrime response capabilities of AFRIPOL member countries,” says Dr Mohammed Benaired, Head, Training and Capacity Building Division at AFRIPOL.

In 2024, to further enhance global efforts to combat cyber offenses, Kaspersky and AFRIPOL signed a cooperation agreement in preventing and fighting cybercrime.

Covering a period of five years, the document formalises and facilitates cooperation between the company and the law enforcement agency in sharing threat intelligence data on the latest cybercriminal activities and entails the provision of assistance and know-how in information security analysis.

Kaspersky Expert Training is used by numerous organisations and academic institutions to advance their skills in battling against cybercrime. Since the inception of this online training programme, Kaspersky experts have trained more than 3,000 specialists from 50 countries around the world.

Providing their expertise with 12 educational courses, they share their insights on advanced tactics and strategies in Reverse Engineering, Threat Hunting, Incident Response and more – each divided by the level of students’ experience.

Nigeria has emerged as the largest investor in artificial intelligence-driven surveillance systems on the continent, committing over $470 million to advanced monitoring technologies, according to a new report.

Nigeria Spends $470m on AI-powered Surveillance Devices- Report

The study found that Nigeria, alongside 10 other African countries, has collectively spent no less than $2.1 billion on AI-powered surveillance infrastructure.

AI-powered surveillance devices represent a significant shift from passive recording to active, real-time monitoring and threat detection

The study, described as the most comprehensive account of smart city surveillance in Africa, examined deployments in Algeria, Egypt, Kenya, Mauritius, Mozambique, Nigeria, Rwanda, Senegal, Uganda, Zambia and Zimbabwe.

These investments include facial recognition systems and automatic number plate recognition tools aimed at strengthening security and urban monitoring.

The report, titled “Smart City Surveillance in Africa: Mapping Chinese AI Surveillance Across 11 Countries,” was produced by the Institute of Development Studies and released in March 2026.

It highlights Nigeria’s position at the forefront of adopting smart surveillance technologies, reflecting a broader trend across Africa where governments are increasingly turning to AI solutions to address security challenges and improve urban management.

“This level of expenditure translates into an average spend in the region of $240m per country.

“Nigeria alone has documented public expenditure of $470m AI-enabled facial recognition and ANPR, making it the continent’s largest buyer of smart city surveillance technologies,” the report stated.

“In all cases, we know that the real total is significantly higher because surveillance spending is often secret; no figures were available for two of the 11 countries studied; the public accounts for the other nine countries were incomplete; and this study included only 11 of Africa’s 55 countries,” the researchers noted.

The report said most of the surveillance infrastructure deployed across the countries was supplied by Chinese firms and financed through soft loans from Chinese banks.

“The Chinese safe city surveillance package is typically financed by soft loans from Chinese banks.

“A typical package involves a loan of $250m from Eximbank tied to the purchase of surveillance cameras from Hikvision and a command and control centre built and serviced by Huawei or ZTE,” it said.

The report explained that the packages usually include thousands of smart closed-circuit television cameras capable of transmitting geo-located facial recognition and vehicle number plate data in real time.

“The Chinese safe city package typically includes installing thousands of smart CCTV surveillance cameras, which transmit geo-located facial recognition and car number plate data in real time for analysis using artificial intelligence at dedicated data centres that serve as command and control facilities for police and security operatives,” the report added.

The study further revealed that China supplied smart city surveillance technologies to all 11 countries reviewed, while South Korea and Russia supplied three countries each, and the United Arab Emirates supplied two.

It added that the actual spending across the region could be significantly higher due to secrecy around surveillance budgets and incomplete public financial records.

The metaverse, championed by Meta (formerly Facebook) in 2021, has largely collapsed due to low user adoption, technical limitations, and massive financial losses exceeding $80 billion.

Metaverse Collapses, Horizon Worlds Shuts Down on Quest

Mark Zuckerberg

Meta is shutting down its flagship VR platform, Horizon Worlds, in June 2026, marking a major shift toward AI and mobile-first strategies.

The app will be removed from the Quest store on March 31 and discontinued in VR by June 15, continuing only as a mobile service.

Horizon Worlds, launched in 2021, was central to Meta’s rebranding from Facebook and its vision of a fully immersive virtual environment.

Despite billions in investment and high-profile partnerships, the platform failed to attract a large user base and struggled with design limitations and weak engagement.

Reality Labs, the division behind the metaverse push, has accumulated nearly$80 billion in losses since 2020, including more than$6 billion in a single quarter.

Recent layoffs affecting around 10 percent of the VR workforce, along with the shutdown of related projects, underscore a broader pullback.

Competition and shifting priorities have accelerated the decline.

Rival platforms such as VRChat maintained stronger communities, while Meta increasingly redirected resources toward AI and hardware, including its Ray-Ban smart glasses.

Although Meta says it remains committed to VR, the closure of Horizon Worlds signals a strategic reset.

The company is repositioning its future around AI-driven products, marking a decisive shift away from its earlier metaverse vision.
