Lydia founded the Mizuho Gender Network in 2017, which has since been enlarged through merging with the gender networks of Mizuho subsidiaries. Lydia, who now co-leads the network, has organized speaker events, driven policy change, with a focus on parental leave, and supported the re-launch of the mentoring scheme. She has secured funding for an external events program with high-profile speakers, targeting imposter syndrome, careers, performance, mindset and resilience. With a focus on policy change, Lydia is now helping the bank understand the need to collate and analyze employment data, and how to use this to impact decision making. She is also focused on tackling the flexible working policy and expanding paternity leave. Lydia mentors women within Mizuho and through Women in Banking & Finance, and represents the bank at external networks, including WIBF and the Network of Networks.
