International Business Machines (IBM) and UBD collaborate on research projects through the UBD IBM Centre (previously known as UBD-IBM Research Institute). On 15 October 2011, Sultan Hassanal Bolkiah inaugurated the centre. In accordance with the agreement that the Sultan first made public in September 2010, scientists from IBM and UBD collaborated to create climate models based on local climate data. These models integrated hydrological models into weather models, enabling the prediction of floods and the effects of climate change on rainforests. As a result of this collaboration, Brunei is home to the first IBM Blue Gene supercomputer in Southeast Asia.

Located on the UBD campus amid an area of undisturbed heath woodland, the Universiti Brunei Darussalam Botanical Research Centre (UBD BRC) was originally established in 2013. On 3 February 2018, the UBD BRC was opened by Sultan Hassanal Bolkiah, in commemoration of the UBD-organized First International Symposium on "Ethnobotany in the Qur'an and Hadith - An Exploration." This made UBD BRC the nation's first botanical garden. The botanical garden focuses on study, teaching, and protection of the country's flora. It is home to more than five hundred varieties of tropical plants, many of which are indigenous to Borneo and Brunei. Under the direction of UBD's IBER, the UBD BRC conducts research, focuses on research, and is a member of Botanic Gardens Conservation International (BGCI).

The UBD BRC is a 6 hectares (15 acres) site that is situated in a tropical lowland heath forest that the locals refer to as Kerangas forest. The Iban term "Kerangas" denotes territory where hill rice is unable to thrive, signifying the deficient nutritional content of the soil in heath forests. Less than 1% of Brunei's forests are Kerangas forests, which are extremely uncommon. Kerangas forests are more susceptible to forest fires due to their drier ecosystems. Additionally, invasive species like Acacia trees can invade damaged Kerangas forests.

High conservation significance native species found in Kerangas woods include Gymnostoma nobile and Agathis borneensis, which are regarded as indicators of pristine Kerangas forests.  More than 500 species of tropical plants, majority of which are indigenous to Brunei and Borneo, are now housed in the live collections at the UBD BRC. The UBD BRC, a research center dedicated to native plant conservation, collaborates closely with regional partners and stakeholders to support Brunei's efforts to realise Wawasan Brunei 2035 and the Sustainable Development Goals 25 (Life on Land) and 23 (Climate Action).

Maung Zarni, co-founder of the Free Burma Coalition, was employed as an assistant professor of Asian studies at UBD. However in January 2013, he had to quit due to restrictions on his public comments against the Rohingya massacre in Myanmar. He attributed the situation to "extreme and unprofessional academic censorship" and stated it is "impossible to maintain his professionalism." He claims to have taken part in a London School of Economics (LSE) panel on human rights and the rule of law in June 2012. Aung San Suu Kyi attended the panel while traveling around Europe. He claims that as a kind of punishment, UBD withheld institutional and financial assistance from him 24 hours prior to his departure to London, forcing him to take personal leave and cover the US$3,000 airfare on his own. The Human Rights Resource Centre for ASEAN has reported that as a result of this incident, scholars at Bruneian universities are expressly obliged to engage in self-censorship when discussing topics related to Islam and the monarchy.
