Tanya Gross is a Senior Managing Director at Ankura, based in London. She has spent the past decade managing investigations and disputes that involve data (unstructured, structured, and semi-structured formats). She has led large scale evidence and disclosure management exercises in the UK, France, Switzerland, Hong Kong, Japan, the Middle East, and the US.


Tanya co-leads the data & technology practice. She also leads the team’s client delivery and practice development efforts across Europe, the Middle East and Africa (EMEA), and Asian Pacific (APAC), including eDiscovery, digital forensics, information security, structured analytics, and custom solutions.

One of Tanya’s strengths is leading and developing teams. She contributed to the growth and expansion of Navigant’s London team, ensuring the delivery a broad variety of work in line with the global practice, and more recently Tanya spent time in Hong Kong to set up Navigant’s Legal Technology operations in the region, also acquired by Ankura. This provided the global team with a regional base to deliver work, expanding upon the teams’ global presence through the implementation of 24/7 working, delivering seamless support to clients where large data volumes exist.

As an accomplished practitioner, Tanya is able to convey the technical detail in a language her clients understand. Having worked in the industry for a long period, Tanya has a thorough understanding of the challenges involved in managing large scale data management exercises and has become a trusted advisor in her field. Her experience covers a wide variety of clients in both the private and public sector, including financial services, construction, retail, and manufacturing, and a wide variety of issues including arbitration, litigation, intellectual property, fraud, antitrust/competition, regulatory, and employment matters.

Tanya’s professional experience includes:

  • Tanya has worked on several data consulting engagements in the financial services and energy sector, all of which have involved assessing how clients can improve their data harvesting techniques and e-discovery processes by providing recommendations to reduce cost and mitigate risk.
  • Tanya worked on a consulting engagement with a large energy organization. This involved assessing their historical approach to e-discovery, understanding their policies around information and data governance, and providing recommendations on their approach to e-discovery going forward. This involved information gathering, interviewing stakeholders, and providing a report of recommendations to their general counsel.
  • Tanya provided executive level oversight on a criminal investigation at a media company which resulted in the capture and restoration of over 20TB’s of data from the company’s systems and back up tapes in response to allegations of bribery of senior public officials and phone hacking. Tanya led the work and regularly had to update the lawyers and Metropolitan Police on the team’s findings. This work has resulted in a large civil investigation where individuals affected are claiming compensation against the media company.
  • Tanya provided senior oversight on a large-scale data collection work-stream involving 240 custodians at a UK retail giant in response to a tribunal into employee remuneration. She worked closely with the project manager to design the process for data capture and ensured there was appropriate documentation and workflow steps for the data collection team to follow.
  • Tanya led a large e-discovery investigation in Asia in response to allegations of bribery and corruption by US and local regulatory authorities. This work involved the use of teams in the UK, US, and Asia along with supporting lawyers in the same geographies. The work resulted in the capture of data for over 100 custodians and is set to increase as more information surrounding the allegations is identified.
